Question

What is the slope of the line that contains these points?

х
-1
0
1
2
y
10
18
26
34
slope:

Answer 1

8.

Explanation:

The slope =

difference in y coordinates of 2 points / difference in coordinates of corresponding x coordinates.

So taking the first 2 points:

The slope = (18-10) / 0 - (-1)

= 8/1

= 8.

This is confirmed by slope between the second and third points

slope = 26-18/ (1-0) = 8.
