Hello and thank you for posting your question to Brainmass.

I am not sure what exactly you mean by saying x-intercept are the same as the coordinates of the y-intercept, since it can mean that the intercept on the x axis has the same distance from the origin as the intercept on the y axis (case 1), or that the intercept point is common to both the y and x axis (case 2). Hence I solve them ...
