Slope Between Two Points
Given two points and , the slope between these two points is . That is, the slope between two points is the difference between the y-coordinates of the points, divided by the difference between the x-coordinates of the points. For example, the slope between the two points (1, 3) and (5, 6) is . The slope between (-1, -1) and (15, -21) is .
