Question

Which set of parametric equations represents the graph of the following rectangular equation using t=7-x? y=x^2+5

Answer 1

So both x and y need to become equations in terms of t. The first equation you have can easily be rearrange to have an x = . For the second equation, you substitute x into that equation. So when you finish youll have an x = and a y =, both of them being equations of t. If that makes any sense.
