The table shows x and y in a linear relationship. How can you tell that x and y are NOT directly proportional?
A x is 0 when y is not 0.
B x is getting farther away from y.
C x and y are moving in different directions.
D x and y are increasing by different amounts.
The correct answer is A: x is 0 when y is not 0.
Explanation: For x and y to be directly proportional, the ratio of y to x must remain constant, which means if x is 0, y must also be 0. If x is 0 while y is not 0, this indicates that there is no direct proportionality between them, as one variable does not depend on the other consistently.
