For each of the following equations, indicate whether its graph would be a line or a parabola.

Hint (a-d):

If the graph of an equation is a line, it can be written in $y=mx+b$ form.
If the graph of an equation is a parabola, it can be written in $y=ax^2+bx+c$ form.

$5x+2y=7$

$y=3x^2$

$y=3$

$4x^2+3x=7+y$
