8-100.
  1. For each of the following equations, indicate whether its graph would be a line or a parabola. Homework Help ✎

    1. 5x + 2y = 7

    2. y = 3x 2

    3. y = 3

    4. 4x2 + 3x = 7 + y

A line can be written in y = mx + b form.

A parabola has an x2 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.
5x + 2y = 7

It is a parabola.

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

It is a parabola.
