#### Answer:

(Graph in explanation)

#### Explanation:

First, we need to set the equation so that

For the first equation

For the second equation

Now we can graph this. We graph both equations on the same graph because to solve by graphing, we have to find the point(s) where the two graphs intersect:

The red line represents the equation

The blue line represents the equation

As you can see, the equations intersect at the point

Therefore, the answer is
