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. Edwin
