Question

Which of the following does not describe slope?

A line joining points
A constant rate of change
A proportional relationship
A measure of change

Answer 1

I think it would be A. Sorry if I'm wrong. 

Answer 2

A. A line joining points.

Explanation:

The following does not describe slope:

A line joining points.

Slope is found by dividing the difference of the y-coordinates of two points on a line by the difference of the x-coordinates of those same two points.

Or in other words, it is defined as the ratio of the vertical change between two points to the horizontal change between the same two points.
