You can find the slope graphically or algebraically. Since you are given a graph here , it will be quickest to find it using the graph. But either way, the slope is: the rise over the run Using the graph, count the number of integers you go up. That will be the rise. Put this number over the number of integers you go either left or right. If you go right, the slope will be positive. If you go left, the slope will be negative.

ok well it goes left and their are two negatives

The intercept values are not that important here, unless you want to solve this algebraically. But it is quicker to do this graphically. If you start at point (0, -3), which is the y-intercept, and then you go up 3 to (0, 0), which is the origin, you are going up "3". That is the "rise". If you go over to the left, you will be at the x-intercept, (-1, 0) and that is "-1" because you went to the left "1". So, your slope is 3/(-1)

It is definitely NOT "c".

So, now, after reading how to get the slope, and given that it is 3/(-1), all you have to do is simplify 3/(-1).

3/(-1) = (-3)/1 = -3
