From the data shown in the scater plots, the points are scattered apart which means that r is not close to 1.
Also the data points increase to the right which means that r is positive.
Therefore, the estimate for r in the data shown in the scatter plot is 0.55
First, move like terms on one side. Next, add them and divide. See the attachment for solution.
Substitute
12(3) + (52)
12(3) = 36
36 + 52 = 88
