Firstly, we need to prove whether or not the curve and straight line actually intersect at all by using the discriminant. Remember to make the RHS of both equations equal to each other first.

Save guides, add subjects and pick up where you left off with your BBC account. The equation of a straight line can also be written in the form \(f(x) = mx + c\). This is called function notation ...

to arrive at the geometric equation for the line, either through manual calculations or by using software. A straight line will result from a simple linear regression analysis of two or more ...
