A 2-column table with 3 rows. Column 1 is labeled x with entries 16, 32, 48. Column 2 is labeled y with entries 1, 2, 4.

• No, as x= 4 ⇒ y =64 not 48

A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 5, 6. Column 2 is labeled y with entries 5, 20, 30.

• No, as x = 5 ⇒ y = 25 not 20

A 2-column table with 3 rows. Column 1 is labeled x with entries 14, 28, 42. Column 2 is labeled y with entries 2, 4, 6.

• Yes, as 2*7 = 14, 4*7= 28, 6*7= 42

A 2-column table with 3 rows. Column 1 is labeled x with entries 0, 1, 3. Column 2 is labeled y with entries 25, 70, 90.

• No, x = 3 ⇒ y= 25+3*45= 160 not 90
