$m=0$

Work Step by Step

RECALL: The slope $m$ of a line that passes through the points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula: $m=\dfrac{y_2-y_1}{x_2-x_1}$ Substitute the x and y coordinates of the given points to obtain: $m=\dfrac{-2-(-2)}{6-3} \\m=\dfrac{-2+2}{3} \\m=\dfrac{0}{3} \\m=0$
