Question

What type of line is the graph of 4x + y = -3?

Answer 1

I'd suggest you look at the POWERS of x and y that are present here.
If both powers are 1, this 4x+y=-3 is a straight line.
If one power is 1 and the other is 2, we have a parabola.

I'd suggest you ask your question in this way: "What shape has the graph of 4x+y=-3?"

Why? because your "What type of line is the graph of ... " gives away the shape: it's a line.

Answer 2

thanks
