X-Intercept

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

Start with the given equation.

Plug in .

Multiply and 0 to get 0.

Simplify.

Divide both sides by to isolate .

Reduce.

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.

Simplify.

Divide both sides by to isolate .

So the y-intercept is

or in decimal form (0, 2.25).

Notice that if we graph the equation , we can see that the graph has the x-intercept

and the y-intercept

, or (0, 2.25)
