Question

A scatter plot has a line of best fit with the following points on it, what is the slope of the line?

(2, 4), (6, 12)

Answer 1

m = 2

Explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)

(2, 4), (6, 12)

We see the y increase by 8 and the x increase by 4, so the slope is

m = 8/4 = 2

So, the slope of the line is 2
