Answer:

(-1,0) see attached graph

Explanation:

To solve the system, graph the two equations.

y = -3x -3 has m=-3/1 and b=-3. Start at (0,-3) on the y-axis and plot a point. Then move down three units and 1 unit to the right. Plot a point and connect.

y=2x+2 has m =2/1 and b=2. Start at (0,2) on the y-axis and plot a point. Then move up two units and to the right 1 unit. Plot a point and connect.

The solution is the point (x,y) where the two lines intersect. By the graph below it is (-1,0).
