Start with the given equation.

Add 4x to both sides.

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 (you can start with any number, but zero is the easiest number to work with since anything multiplied by zero is zero)

Multiply and to get

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

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
