Which table shows a proportional relationship between x and y? A:
x 2 3 4 5
y 7 9 11 13
B:
x 3 7.5 15 20
y 1 2.5 4 6
C:
x 1 2 7 8
y 0.5 1 3.5 4
D
x 3 6 8 10
y 12 15 18 20

I used all my points so I better get an answer QUICK

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
