As the equation is already in y=mx+b, all we need to do is use the equation to draw out a graph (or in this case, match with an already existing graph) using the y-intercept and slope. Since the y-intercept is 5, we can eliminate graphs C and D from our answers. We know the slope is -4, which means that our rise over run is -4 over 1. That would mean, to get from one point to the next, you go down 4 spaces and to the right one. This means the correct answer is graph B.
