so the closer to 1 the higher the correlation or the closer the dots are to each other.
a) -0.97
the dots should have a relatively negative slope and close together. the last graph fits this best.
b) 0.16
the dots should not really have a linear relationship and would look a bit disordered. this would best fit the first graph
c) 0.17
like b, this would be a bit disordered but there should be a more visible linear pattern amongst the dots, which i believe the second graph seems to fit the best.
d) 0.89
there would be a positive linear relationship amongst the dots and they should be relatively close together which fits the third graph best.
b and c are very similar, and to me the first graph fits b better, however if you believe the second is less of a linear relationship compared to the first one, put that as b
