Find two vaules for

#### Explanation:

**The easiest method is by finding two coordinates.**

Find two vaules for

To find a co-ordinate, we must pick any

Let's pick

Then substitute into the equation:

So the first coordinate is

Then repeat picking a different

Assume

Second coordinate:

Then simply sketch a line between
