Question

Which table does not represent a proportional relationship? A 2-column table with 3 rows. Column 1 is labeled x with entries 9, 6, 3. Column 2 is labeled y with entries 3, 2, 1. A 2-column table with 3 rows. Column 1 is labeled x with entries 16, 18, 20. Column 2 is labeled y with entries 4, 4.5, 5. A 2-column table with 3 rows. Column 1 is labeled x with entries 12, 18, 22. Column 2 is labeled y with entries 2, 3, 4. A 2-column table with 3 rows. Column 1 is labeled x with entries 5, 7, 9. Column 2 is labeled y with entries 10, 14, 18.

Answer 1

12, 18, 22

Explanation:

Answer 2

the one with 12, 18, 22

Explanation:

in the first one, 9-3=6 and 6-3=3 so -3 is the constant of the proportionality

in the second one 3-1=2, 2-1=1 so here the constant of proprtionality is -1

in the third one 16+2=18, 18+2=20 so the constant of proportionality is 2

fourth one 4 + 0.5= 4.5 and 4.5+0.5= 5, constant of proportionality is 0.5

fifth one 12+6=18, but 18+6=24

and the rest are all proportional
