Each of the number pairs are x and y coordinates, of the form (x,y). x is the horizontal distance, and y is the vertical distance. The slope of the line where you know two points is the change in the y coordinate divided by the change in the x coordinate. Since the y coordinate is 4 in both cases, it doesn't change, and the line is perfectly horizontal for a slope of 0. The formula goes something like this:
(y2 – y1)/(x2-y1)
To use the formula, the first (x,y) pair is (3,4) and the second is (-2, 4), so the answer is:
(4-4)/(3-(4)) = 0/7=0
I have no clue what any of this means though.
