So the equation ($y=\frac{9}{4}x-4$) is already in y=mx+b format.
=> Where $\frac{9}{4}$ is the slope, m.
=> Where −4 is the y-intercept, b.
All we have to do is graph it.
I think what you have difficulty with, is the slope. You can use the $\frac{\text{rise}}{\text{run}}$ method to graph the slope.
Basically, all numerators are rise, and all denominators are run. So in this case, starting at (0,−4), move up 9 points, then right 4 points, giving us (4,5).
You also do the opposite: starting at (0,−4), move down 9 points, then left 4 points, giving us (−4,−13).
