Answer
slope = 0
Refer to the graph below.
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{−1−(−1)}{−3−2}=\dfrac{0}{−5}=0 $
(ii) Plot the points on the same coordinate plane , then connect them using a straight line to complete the graph.
