Work Step by Step

RECALL: The slope $m$ of a line can be found using the formula $m=\dfrac{y_2-y_1}{x_2-x_1}$ where $(x_1, y_1)$ and $(x_2, y_2)$ are points on the line. (i) Using the two given points on the line, solving for $m$ gives: $m=\dfrac{(2-0)}{2-2}=\dfrac{2}{0}$ (slope is undefined) (ii) Plot the points on the same coordinate plane, then connect them using a straight line to complete the graph.
