Step-by-step explanation:
It is convenient to graph this equation using the x- and y-intercepts.
The x-intercept is found where y=0, so ...
4x = 36
x = 9
The y-intercept is found where x=0, so ...
-6y = 36
y = -6
<em>Graph the two points (9, 0) and (0, -6) and draw a line through them</em>. The graph is shown below.
