Finding the intersection point of two graphs

[jekoddragon]

It's not actually hard to remember what you have to substitute. The X axis is a line where every Y coordinate equals 0 (because X varies and Y stays the same) - and the Y axis is a line where every X coordinate equals to 0. If you want to find the point of interception with the X axis, then you know that the points' Y coordinate must be 0. Similarly with the point of interception with the Y axis.

I'd have used Gaussian elimination. You know, linear algebra on a tensor. This non-computer science old school maths approach is unduly confusing. And it's computationally expensive. What's the big O on all this?
