Step-by-step explanation:
<em>If the rate is a constant, the relationship is proportional.</em> (The rate is the constant of porportionality.)
_____
For two or more points on the function curve, divide the dependent variable value by the independent one. If you get the same result in every case, the relationship is porportional.
___
<em>Note</em>
For some non-proportional relationships, it is possible to find points on the graph that will pass the above test. If you suspect the relationship is actually not one of proportionality, try more points. Check also to make sure that (0, 0) is on the curve.
Answer:
60 cubic centimeters
Step-by-step explanation:

Correct option - B
Let's check all of them
A. 93 x 1 = 93 its not equal to -93
B. 31 x -3 = -93 ,this one matches
C. -31 x -3 = 93, again not equal
D. -93 x -1 = 93, not equal
So the answer is B
