Answer
We draw a line that goes through the point $(0,-6)$ and the point $(2,-3)$.
Work Step by Step
Using the method in example three, we first put the equation in slope-intercept form. $y = \frac{3}{2}x -6$
We then graph the y-intercept, which in this case is $(0,-6)$.
Next, knowing that the slope is equal to rise over run (the slope is 3/2 in this case), we go up 3 and over 2 to the point $(2,-3)$. We then draw a line through both of the points that we graphed.
