Answers:

Graph BChoice C) y = 0.13x - 0.19

Explanations:

Notice how all of the points in graph B are near to a single line. This is the regression line. We don't have every point on the same line, but it's close enough. Graph A seems to suggest an exponential growth curve could work as the regression curve. Graph C seems to be randomly scattered points, so perhaps no function would work as the regression curve.I used technology to get the regression line. Specifically, I used GeoGebra. Any spreadsheet program or graphing calculator should be able to find the regression line. You can do so by hand, but I don't recommend it because it's tedious busy work in my opinion.

Is there a picture of a graph or whatever that goes along with this?
