Y 4 6 7 10

C. X -3 -2 0 4
Y -12 -8 0 16

D. X -6 -2 0 8
Y -5 1 4 16

Answer 1

ANSWER IS C

A:

7 divided by -6= -1.16666666667

9 divided by -3= -3

3 divided by 6= 0.5

-3 divided by 15= -0.2

A does not have a proportional relationship.

B:

4 divided by -3= 1.33333333

6 divided by -1= -6

7 divided by 1= 7

10-3= 3.33333333

B does not have a proportional relationship.

C:

-12 divided by -3= 4

-8 divided by -2= 4

0 divided by 0= 0

16 divided by 4=

C DOES have a proportional relationship.

D:

-5 divided by -6= 0.833333333

1 divided by -2= -0.5

4 divided by 0= 0

16 divided by 8= 0.833333333

D does not have a proportional relationship.

To find a proportional relationship, you have to divided y and x together. If you have the same unit rates when you divided all y's and x's with each other, then that's a proportional relationship. if not, then it's not a proportional relationship.

Hope this helps :) Sorry it's long.
