Really, there is no need for the dollar marks " $ " around numbers.



Find the x-intercept by substituting y=0 in the equation and solving for x.
Find the y-intercept by substituting x=0 in the equation and solving for y.

They will be fractions.

Now you have a right triangle formed, so use the Pythagorean theorem to
find the distance between the x-intercept and the y-intercept. It will
be the hypotenuse. Or if you've studied the distance formula, you can use 
that.

Hint #1: The x and y intercepts are (8/3, 0) and (0, -8/3) in that order.

Hint #2: The distance formula is d+=+sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29
