I mean I can graph any of the equations from the book but now it's showing me how to find the x and y interceps when they equation is in the form

$\displaystyle \frac{x}{a} + \frac{y}{b} = 1$ where the x and y intercep is b.

I really can't be bothered to keep going through all these varies methods, when I come to higher mathematics, will I come across this equation in many many different forms and is it worth learning them all?
