Match the linear correlation coefficient to the scatter diagram. The scales on the x- and y- axes are the same for each diagram. ( a) r = - 0.969 ( b) r = - 0.049 ( c) r = - 1 ( d) r = - 0.992 Response Explanatory ( I)

Well, without seeing the diagrams:
 
(A) r = -.969 --> points will be tightly scattered about a line with slope -1
 
(B) r = -.049 --> points will almost have no pattern at all
 
(C) r = -1 --> points will all lie on a line with slope -1
 
(D) r = -.992 --> points will be almost completely on a line with slope -1
