Question

Which of the following does NOT describe slope?

A- A rate of change
B- Rise over run
C- A proportional relationship
D- A line

Answer 1

Honestly, all of these answers seem correct. However, D. a line seems to be the most inaccurate option because it is very vague and would not be able to describe a slope as efficient as the others would. 

Answer 2

D- A line

Explanation:

Slope is a rate of change, so A is correct.

Slope can be found on a graph by counting the vertical change (rise) over the horizontal change (run); B is correct.

Slope is a proportional relationship, so C is correct.

A line does not describe slope. Slope is a measure of a line, but a line does not describe slope. D is not correct.
