1. OBJECTIVE: USE THE SLOPE INTERCEPT FORM TO GRAPH A LINE Slope Intercept Form

2. Slope & Y-Intercept m = slope b = y-intercept

3. Verify Points on a Line Determine whether (3,-5) lies on the graph of y = -3x + 4

4. Verify Points on a Line Determine whether (8,4) lies on the graph of 3y = 2x -1

5. Verify Points on a Line Determine whether (5,-7) lies on the graph of 3y + 5x = 4

7. Graphing Steps 1. Write the equation in slope intercept form 2. Identify m and b 3. Plot the y-intercept (0,b)

8. 4. Start at the y- intercept,find another point on the line using the slope 5. Draw the line

9. y = 5x -4 Start at the point (0, -4) Plot another point on the line using the slope (m = 5) Rise five units up Run one unit to the right

10. Start at the point (0, 2) Plot another point on the line using the slope (m = -3/4) Rise 3 units down Run 4 units to the right

11. Graph Using m and b m =-1 b = 4

12. Graph Using m and b m = 3/4 b = -5

13. Graph Using m and b m =-1/5 b = 1
