Answer:
To find a point that belongs to the graph, you have to assume the value of one variable and compute the other one. For example, if x = 0, then y = -3 -0 = -3. Similarly:
x y
0 -3
1 -4
2 -5
To make the graph, locate the previous points on the coordinate plane and then draw the line that passes through them (see figure attached)
