You can find the slope of a line by using the formula m = y_2 - y_1 / x_2 - x_1, where m is the slope and x and y are the given coordinates.
m = y_2 - y_1 / x_2 - x_1 Plug in the given coordinates m = 3 - (-3) / 7 - 5 Cancel out the double negative m = 3 + 3 / 7 - 5 Add and subtract m = 6 / 2 Simplify m = 3
