- B (^ 2 = exponential change)
- D (constant y = horizontal line)
- C (linear gradient)
- A (constant x = vertical line)

Equation 1 is line B because we directly changing the X value (^2)

Equation 2 is line D because Y is constant

Equation 3 is line C because we are not changing the X value so we will have a slope

Equation 4 is line A because X value is constant

1) B

2) D

3) C

4) A

Because in 1 you change X directly in 2 y is constant, in 3 x is not changed directly, and in 4 x is constant.
