Slope, Slope-Intercept form, and Standard form

1. Bellwork Solve for x Solve for y

2. 1. IWBAT find slope and y-intercept using the slope-intercept form. 2. IWBAT write the equation of a line from given information.

3. Slope-Intercept Form linear equation : y = 3/2x + 3, y = -5x - 2 (not all equations are linear) y-intercept : y-intercept : crosses the y axi s

4. Slope-Intercept Form y-intercept, substitute, slope, y-intercept

7. Bellwork y = mx + b 1. What does the "m" stand for? 2. What does the "b" stand for? 3. Solve for y. 3y = 2x + 6 4. Solve for y. Then find the slope and y- intercept. 5y = 7x - 10

8. Write an equation of the line with slope 3/8 and y- intercept 6. Write an equation of the line with slope -3 and y- intercept 4.

9. Writing an equation from a graph Step 1: Find slope. Step 2: Use slope- intercept form.

10. Write the equation of the line.

11. Bellwork Write the equation of the line. What is the slope and y-intercept of: y = mx + b

12. 1. IWBAT graph linear equations using the slope-intercept form and standard form. 2. IWBAT transform linear equations from standard form to slope-intercept form.

13. Graphing equations Graph y = 3x - 1 Graph y = 3/2x - 2

14. 1. Solve for y, then graph the line. 3y = 4x - 6

15. Using standard form Ax + By = C Find the "x" and "y" intercepts of 3x + 4y = 8. Graph the line.

16. Find the x- and y- intercepts of 2x + 3y = 12. Graph the line.

17. Find the x- and y- intercepts of 5x -- 3y = 15. Graph the line.

19. Transforming to standard form Write y = 3/4x + 2 in standard form using integers. Multiply both sides by denominator using distributive property Distribute Move x term to the left side.

20. Transform y = -2/5x + 1 into standard form. Transforming to standard form
