Solution

An exact negative linear relationship. is -1.00. This is because - shows negative relationship and 1.00 is the magnitude which shows perfect/exact relationship.

A very strong positive (but not exact) relationship, which is approximately linear. is +0.97. Since the sign is +, the reltionship is positive. A magnitude of 0.97, which is very close to 1.00 gives a very strong, approximately linear relationship.

No obvious relationship.is +0.09. A low magnitude of 0.09, closer to 0, shows no obvious relationship.

An obvious negative linear relationship about which the points are quite widely scattered. is -0.66. Since the sign is -, the relationship is negative, A magnitude of 0.66 which is neither very high or very low, shows that points are widely scattered.
