Question

What is the slope of the line that contains the points (–2, 7) and (2, 3)?

A. 4

B. 1

C. –4

D. –1

Answer 1

D. -1

Explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(3 - 7) / (2 + 2)

-4 / 4

= -1

So, the slope is -1.

The correct answer is D. -1
