Rearranging to Graph Using y = mx + b Method 1. Rearrange the equation to y = mx + b form 2. Plot the y-intercept (Plot b on the y-axis) 3. Use the slope to plot another point (ex. For m = ¾ go up 3 and right 4) Example 1: Rearrange the following equations into y = mx + b form and graph using the slope and y-intercept a)

-3x + 2y – 2 = 0

2)

x – 4y – 8 = 0

3)

2x + y + 3 = 0

4)

2x + 3y – 6 = 0

5)

3x – y – 1 = 0

6)

-3x – 5y – 10 = 0
