Question

What's a linear function?how do you know if it represents a linear function?

Answer 1

Sounds hard. Good luck!

Answer 2

So it's B, since you have both variables of x and y. And you can get y alone, to get a constant for x, which is what makes it linear. It can't be A since the x is squared, and on a graph it's a curved shape (parabola) so it is nonlinear
