#### Answer:

#### Explanation:

First rearrange the two equations so

Because these are straight lines, we only need to put in two values of

So we have coordinates

So we have coordinates

We now plot each pair of coordinates and join them with a straight line.

You should have a graph that looks like this:

We can see from this that, at the intersection the
