Which answer is the best estimate of the correlation coefficient for the variables in the scatter plot?
a. -0.95
b. -0.5
c. 0.5
d. 0.95

I think the correct answer would be -0.5. It would be the best estimate since looking at the graph the points tend to have a negative correlation where as Y increases the value of X decreases. However, the value of the correlation would be small since the points are very varied. Hope this helps.

A’b’c’ are the coordinates to the new location of the transformed triangle abc. find the distance between the coordinates points to use for your calculations.
