Step-by-step explanation:

just took the quiz and got it right

y = 42

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use an ordered pair from the table.

Using x = 2 when y = 12, then

12 = 2k (divide both sides by 2)

6 = k

y = 6x ← equation of variation

When x = 7, then

y = 6 * 7 = 42
