Question

Determine whether the points on the line rise, fall, are horizontal, or vertical.

(2, -4) and (4, -1)

Answer 1

The points rise.

Explanation:

Points on a line have the following format: (x,y)

They rise if: As x increases, so does y.

They fall if: As x increases, y decreases.

They are horizontal if: As x increases, y remains constant.

They are vertical if: x is constant as y changes.

In this question:

Points (2,-4) and (4,-1).

x increases from 2 to 4.

y increases from -4 to -1.

That is, both increase, so the points rise.
