Start with the given equation.

Add to both sides.

Rearrange the terms.

Divide both sides by to isolate y.

Break up the fraction.

Reduce.

In order to graph this equation, we only need two points to create a straight line

--------------------------------Let's find the first point--------------------------------

Start with the given equation

Plug in

Multiply and to get

Add

Reduce

So when , we have the value . This means we have the first point

--------------------------------Let's find the second point--------------------------------

Start with the given equation

Plug in

Multiply and to get

Add

Reduce

So when , we have the value . This means we have the second point

------------------------------------------------------------------------------------------------

So we have the two points:

and

Now plot these two points on a coordinate system

Now draw a straight line through the two points. This line is the graph of

Graph of through the two points

and
