Transcript

• 1.
• 2.
• Our body systems are interconnected and dependent on
• each other!
• It takes all the systems for human
• growth and development.
• How is this related to a system of linear equations?
• 3.
• Think back to linear equations!
• Given y = 2 x – 3, a &quot;solution&quot; to this equation was any ( x , y ) point that &quot;worked&quot; in the equation, made the equation TRUE!
• y = 2 x – 3
• 1 = 2(2) – 3
• 1 = 4 – 3
• 1 = 1
• (2,1) is a solution since the statement is true!
• 4.
• 5.
• Graphing is one of many methods used to solve a linear system.
• Solving Linear Systems by Graphing
• 6.
• Linear Systems
• Intersect at (3,0)
• 7.
• 8.
• The equations must be in slope-intercept form: (y = mx + b)
• Graph the system.
• Find the point(s) of intersection.
•
• If they DO NOT INTERSECT …
• PARALLEL Lines produce NO SOLUTION b/c there are NO POINTS in common!
• SAME Lines produce MANY SOLUTIONS b/c they share ALL POINTS!
• 9. After reading the material in this topic, it is time to check your knowledge.  You may repeat the practice until you have received a score of 80 or above! Once you have successfully completed this assignment, you can move to the Mastery Assignments.
