Start with the given equation

Rearrange the terms.

x-intercept

To find the x-intercept, plug in and solve for x

Start with the given equation.

Plug in .

Add 3 to both sides.

Divide both sides by -3 to isolate x

So the solution is

So the x-intercept is

.

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

y-intercept

To find the y-intercept, plug in and solve for y

Start with the given equation.

Plug in .

Multiply and 0 to get 0.

Combine like terms.

So the y-intercept is

.

So we have these intercepts:
x-intercept:

y-intercept:

Now plot the two points

and

Now draw a line through the two points to graph
graph of through the x-intercept

and the y-intercept
