Answer: do you have a picture of the assignment?
Step-by-step explanation:
Solving the equation for y puts it in slope-intercept form.

This tells you one point can be plotted on the y-axis at y=-1. Another point can be plotted 3 units up and 5 units to the right of that one, at (5, 2). The graph is the line through those points.
Since you're asked to plot at least 3 points, your third point could be 5 units left and 3 units down from the first one, at (-5, -4).
