So the equation () is already in y=mx+b format.
=> Where 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 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).
