100% because

is 6 and

is 9 meaning that the sum will come up at 6 or 9 also meaning that its 100%
because the y-intercept is 3, you'll place your first point up 3 on the y-axis (so (0, 3)). From there you can use your slope to graph the rest
Because your slope is -6, rise over run tells you it's pretty much -6/1, thus, from the point you placed on the y-axis you go down 3 places, and to the right 1. This makes your next point (-3, 1). For your last point you use your rise over run vice versa and go up 6 places, and to the left 1. This point would be (8, -1). If you connect these 3 points you'll have a pretty good graph
