2. Starter Find the slope and y -intercept 1.) y = 3x -2

3. Slope is 3 y -intercept is -2

4. 2.)Find slope & y-int Y-intercept is 2 Slope is 2

5. Write an equation of the line 1.) If the slope is 5 and the y-intercept is 3 y = 5x + 3 2.) If the slope is -2 and the y-intercept is 2. y = -2x + 2

6. Today’s Objective To be able to write an equation of a line in the slope intercept form.

7. Write an equation of the line 1.) If the slope is 1/3 and the y-intercept is -2. y = 1/3x -2 2.) If the slope is -3/4 and the y-intercept is 6. y = -3/4x + 6

8. You try these, Write an equation of the line 1.) If the slope is -3 and the y-intercept is 2. 2.) If the slope is 1/2 and the y-intercept is 0. 3.) If the slope is -1 and the y-intercept is 3/4.

9. Write an equation of the line 1.) If the slope is -3 and the y-intercept is 2. y = -3x + 2 2.) If the slope is 1/2 and the y-intercept is 0. y = 1/2x

10. Write an equation of the line 3.) If the slope is -1 and the y-intercept is 3/4. y = -x + 3/4

11. Write an equation of the line by finding the slope and y-intercept y-intercept = 4 Slope is up 2 left 2 = -1 y = -x + 4
