1. You start at (0,-3) because the last number in slope intercept form (the equation above) represents the y intercept.
2. Plot a point at (0,-3).
3. The 3/2 represents the slope, so from (0,-3), go up 3 lines and right 2 lines. Keep plotting the points. You can also go down 3 and left 2.
4. Make a line from the points.
