#### Answer:

↓See below↓

#### Explanation:

A linear graph needs to have the

To isolate

We have our first graph ↓

graph{y=-2/3x-2 [-10, 10, -5, 5]}

To graph our second equation, let's subtract

Then, divide by

We have our second graph ↓

graph{y=x/3+2 [-10, 10, -5, 5]}

Combine the two graphs.

The point where the 2 graphs intersect is the solution to this system of equations.

graph{(y-x/3-2)(y+2/3x+2)=0}
