Eyeball-estimate the regression line for the following scatterplot. Then determine the slope of that line. Select the answer that comes closest to your eyeball-estimate of the slope.

Question

Answer 1

Do the best you can to draw a line going through the middle of all the points like this:

Notice it doesn't actually hit any of the points but there are as many points above as below the line.

Then draw a slope triangle by finding two points on the line like I did and then calculate the slope:

(117 - 70)/(40 - 3) ≈ 1.27
