The document discusses different methods for solving systems of linear equations:
1) Graphing both equations on the same coordinate plane and finding the point of intersection.
2) Using the substitution method, which involves replacing one variable with an equivalent expression containing the other variable.
3) Using the elimination method, which involves adding or subtracting equations to eliminate a variable and then solving for the remaining variable.
The document provides examples of using substitution and elimination methods and discusses the possible solutions when graphing systems of linear equations.

Lightning Talk #9: How UX and Data Storytelling Can Shape Policy by Mika Aldabaux singapore
How can we take UX and Data Storytelling out of the tech context and use them to change the way government behaves?
Showcasing the truth is the highest goal of data storytelling. Because the design of a chart can affect the interpretation of data in a major way, one must wield visual tools with care and deliberation. Using quantitative facts to evoke an emotional response is best achieved with the combination of UX and data storytelling.
Content personalisation is becoming more prevalent. A site, it's content and/or it's products, change dynamically according to the specific needs of the user. SEO needs to ensure we do not fall behind of this trend.
Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
By David F. Larcker, Stephen A. Miles, and Brian Tayan
Stanford Closer Look Series
Overview:
Shareholders pay considerable attention to the choice of executive selected as the new CEO whenever a change in leadership takes place. However, without an inside look at the leading candidates to assume the CEO role, it is difficult for shareholders to tell whether the board has made the correct choice. In this Closer Look, we examine CEO succession events among the largest 100 companies over a ten-year period to determine what happens to the executives who were not selected (i.e., the “succession losers”) and how they perform relative to those who were selected (the “succession winners”).
We ask:
• Are the executives selected for the CEO role really better than those passed over?
• What are the implications for understanding the labor market for executive talent?
• Are differences in performance due to operating conditions or quality of available talent?
• Are boards better at identifying CEO talent than other research generally suggests?

Session One: 'Setting Expectations: a DEIA Primer,' was held June 6, 2024.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. Systems of Equations
Presented by:
Cara Varon
EDUU 551 Applications of Computers
Brandman University
2. Activating Schema
• Chapters 2 and 3: You learned to solve
multi-step problems involving linear
equations and inequalities in one variable
and provided justification for each step.
• Chapter 5: You learned how to graph a
linear equation and compute the x- and y-
intercepts
• Chapter 5: You learned to verify that a
point lies on a line, given the equation of
the line.
3. Vocabulary
Definitions
1. A system of linear equations is a
situation in which two or more linear
equations are together in the same
scenario
2. A solution of the system of linear
equations is an ordered pair in a system
that makes all of the equations true.
4. Solving Systems by Graphing
Steps to follow:
1. Graph both
equations on the
same coordinate
plane
2. Find the point of
intersection
3. Check to see if
the point of
intersection
makes both
equations true
5. Three Possible Solutions of Systems of Linear
Equations
• If the lines have
different slopes, then
the lines intersect, so
there is only one
solution
• If the lines have the
same slope and
different y-
intercepts, then the
lines are parallel and
there are no solutions
• If the lines have the
same slope and the
same y-intercept, then
the lines are the same,
so there are infinite
solutions
6. Solving Systems Using Substitution
• Substitution Method: Another method for
solving systems of equations by replacing one
variable with an equivalent expression containing
the other variable.
• Steps:
1. Write an equation containing only one variable, and solve it.
2. Solve for the other variable in either equation.
3. The solution will be an ordered pair.
4. Check to see if the ordered pair makes both equations true.
**See example on next slide.
7. Example of Substitution Method
Problem: y=-4x+8
y=x+7
Step 1.
Start with one equation. y = -4x+8
Substitute x+7 for y. y+7 = -4x+8
Solve using Equality Properties. x = 0.2
Step 2.
Substitute 0.2 for x in y=x+7. y = -4(0.2)+8
Simplify. y = 7.2
Solution is (0.2 , 7.2)
Step 3. Check
Replace the x and y variable with the solution set.
7.2 - -4 (0.2) + 8
7.2 = 7.2
8. Solving Using Elimination Method
• Elimination Method: Another where you can
use the properties of equality to solve a
system. You can add of subtract equations to
eliminate a variable.
• Steps:
1. Look for coefficients that are opposites or each other. If there
aren’t any, you may need to multiply one or both equations by a
nonzero number. This will to produce coefficients that are
opposites of each other.
2. Eliminate one variable.
3. Solve for the remaining variable.
4. Solve for the eliminated variable using the original equations.
5. The solution is an ordered pair.
6. Check to see if the ordered pair makes both equations true.
9. Example of Elimination Method
Problem: 2x+5y = -22
10x+3y = 22
Step 1:
Eliminate one variable 5 [ 2x+5y = -22 ] 10x + 25y = -110
10x+3y = 22 10x + 3y = 22
0 + 22y = -132
Step 2:
Solve for y. 22y = -132 y = -6
Step 3:
Solve for the eliminated variable using either of the original equations.
2x + 5(-6) = -22 2x – 30 = -22 2x = 8 x=4
The solution is (4, -6 )
