If SS XY = 16.32 and SS X = 40.00 for a set of data points, then what is the value of the slope for the best-fitting linear equation?

If SSXY = −16.32

and SSX = 40.00

for a set of data points, then what is the value of the slope for the best-fitting linear equation?

−0.41

−2.45

    positive

There is not enough information; you would also need to know the value of SSY.
