In this lecture we looked at the linear equation. We also learnt what happens when our lines are horizontal or vertical.

For your challenge, you need to match up the equations to the type of line:

- (x^2 / 4) – 3
- y = ln(4)
- y = x/2 + 2
- x = 1

A. Vertical

B. Parabola (not a straight line)

C. Positively sloped

D. Horizontal
