Answer
$(0,-7),(1,-9),(2,-11)$
Work Step by Step
Answer may vary.
Step 1. Given slope $m=-2$ and point $P(-2,-3)$, we can write the point-slope form of the equation as $y+3=-2(x+2)$ or $y=-2x-7$.
Step 2. Letting $x=0,1,2$ and using the equation, we can locate three more points on the line as $(0,-7),(1,-9),(2,-11)$
Alternatively, one can use the method given in the textbook example to get the same results.
