Question

Find the slope of the line created from the points on the table. A. 1/7 B. -7 C. 2/3 D. - 3

Table:
x y
2 14
3 7
4 0
5 -7

Answer 1

B. -7

Explanation:

Formula to find slope is (y2-y1) / (x2-x1)

Here we have 4 points to choose from, but we only need 2. I will use the first 2 points.

The y2 is 7, the y1 is 14, the x2 is 3, the x1 is 2.

Substitute these numbers into the formula.

(7-14) / (3-2)

^ This is basically -7/1, or -7.
