In the previous section, you learned the definition of slope to be as follows:
Graphically, the slope of a line can be represented using a change in the vertical direction and a change in the horizontal direction.
Given two points (x1, y1) and (x2, y2), the slope of a line can be determined using the formula below.
In the slope formula, y2 - y1 represents the change in y, while x2 – x1 represents the change in x. Let’s practice using the slope formula with the interactive below. Find the slope of the line connecting the points (-4, 7) and (-3, -1). Simplify the numerator and denominator in order to determine the change in the vertical direction and the change in the horizontal direction.
