Using the slope formula for the points (1, 5) and (2, -2), what would the denominator be? -2 - 5 -2 - 1 2 - 1 2 - 5

Hello there! The formula for finding slope is y2 - y1 / x2 - x1, meaning you subtract the first x and y-coordinates, from the second x and y-coordinates. In this case, the formula would be set up as -2 - 5 / 2 -1, because (2, -2) is the second point and (1, 5) is the first point. The answer is C: 2 - 1.
