Step-by-step explanation:
A linear function involves two variables which are in their first power form, such as x and y.
A nonlinear function may include two variables, one or more of which are of the 2nd or higher power.

Answer:

Step-by-step explanation:
we have the expression:

We need to multiply the two terms in the first parenthesis by the two terms in the second parenthesis:

we solve each term taking into account the law of signs
(-)(-)=+
and
(+)(-)=-
also for the first term we use that 
thus we have:

it can be simplified a little more if we factor an r of the second and third term:

These are all points on a graph. I'm not sure what you're asking.
