Final answer:
The equation that would be used to find the horizontal distance between the points (4,3) and (-5, 3) is d = 4 - (-5). To find the horizontal distance, we subtract the x-coordinate of one point from the x-coordinate of the other point. In this case, we subtract 4 from -5, which gives us a distance of 9.
