8-100.

A line can be written in *y* = m*x* + b form.

A parabola has an *x*² in the equation.

Solve the equation for *y*.

If it is a line, it will be in *y* = *mx* + *b* form.

It is a line. 5*x* + 2*y* = 7

It is a parabola.

It is a line.*y* = 3 is the same as *y* = 0*x* + 3

It is a parabola.
