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 .
Reduce.
So the y-intercept is )
.
Now let's plot the points and which are the x and y intercepts respectively.
Now draw a straight line through the plotted points to graph .
