Work Step by Step
To graph the given equation, do the following steps: (1) Create a table of values by assigning $x=-3, -2, -1, 0, 1, 2, 3$, and then solving for the corresponding value of $y$ for each one. (Refer to the table in the attached image below.) (2) Plot each ordered pair (or point), and then connect them using a straight line. (Refer to the attached image in the answer part for the graph.)
