You find slope by choosing 2 points and doing "rise over run" or y/x. By this I mean, you count the distance straight up from one point to the other for y, and count straight across for x. Then divide y by x.
So it would be 4/4 which is 1 so A. However idk why it shows the numbers going up on your y axis are negative.. maybe its just the lines on the next quadrant.
