At the point (or points) where two graphs intersect, the \(x\) and \(y\) values are the same for both functions. We use this information to find the solution to simultaneous linear equations.

In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following ...
