Question

Tell whether the x- and y-values in the table show a proportional or non-proportional relationship. If the relationship is proportional, tell the rule. Select one:

aProportional; x = 3/7y
bNon-proportional
cProportional; x=1/3y
dProportional; x=2/5y​

Answer 1

b. Non-proportional

Explanation:

A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.

The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:

y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4

Therefore, it is non-proportional.
