The scatterplot for a set of data points is shown, along with the line of best fit. choose the best estimate for r, the correlation coefficient.
a) -1.0
b) -0.8
c) 0.8
d) 1.0

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
