Question

Which table shows a proportional relationship between x and y?

Answer 1

Answer: C

Step-by-step explanation:A proportional relationship is a relationship which crosses through the origin (0,0) and which has a proportional constant. We can determine this either by finding (0,0) where x=0 and y=0 in the table or by dividing y/x. None of the tables contain (0,0) so we will divide y by x. We are looking for a table which when each y is divided by its x we have the same constant appearing.

These fractions are not equal. This is not proportional.

x 2 3 4 5

y 7 9 11 13

These fractions are not equal. This is not proportional.

x 3 7.5 15 20

y 1 2.5 4 6

These fractions are not equal. This is not proportional.

x 3 6 8 10

y 12 15 18 20  HOPE IT HELPS:P
