Question

Use technology to find the line of best fit for the following data.

(−7,1), (2,9), (0,7), (−3,5), (−8,−2), (−1,2), (−6,−1), (−5,0), (0,5), (1,7), (−4,2), (3,7)
When the equation of the line is in the form y=mx+b, what is the value of m?
Enter your answer as a decimal rounded to the nearest tenths place, like this: 42.5

Answer 1

m=0.9

Explanation:

Answer 2

Y= 0.9x + 7.2. I just picked two random points that were in the middle of the cluster and wrote an equation for that line.
