4. 6-5 Graphing Linear Equations Objective: To graph a line in point-slope form.

5. Point-Slope Form (x 1,y 1 ) = point M = slope We are going to use these to graph!

6. Steps to Graph 1. Graph the point (x 1,y 1 ) 2. Use slope (as a fraction) to find your next point - rise/ run from the point Example 1: graph y – 2 = 2(x – 1)

7. Example 2 graph y – 1 = 3(x + 4)
