I'm workig through this book I have and an entire chapter is dedicated to y=mx+b equations. I've learnt a few ways of how to work out the graph. Also the book is teaching me a few different ways in which the equation can be structured. It's getting a bit monotonous and I'm bored of this stuff now. The problem is how important is this stuff? 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

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?
