Answer

The graph is shown below.

Work Step by Step

The given equation is $\Rightarrow -2y+12=-3x$ Subtract $12$ from each side. $\Rightarrow -2y+12-12=-3x-12$ Simplify. $\Rightarrow -2y=-3x-12$ Divide each side by $-2$. $\Rightarrow \frac{-2y}{-2}=\frac{-3x-12}{-2}$ $\Rightarrow y=\frac{3}{2}x+6$ The slope-intercept form is $\Rightarrow y=mx+b$ $y-$ intercept is $b=6$. Plot the $y-$ intercept $A=(0,6)$. The slope is $m=\frac{3}{2}$. Slope $m=\frac{rise}{run}=\frac{3}{2}$ The next point is $2$ unit right and $3$ unit up from the point $(0,6)$. Plot the point $B=(2,9)$. Draw a line through the two points.
