Given:

y varies directly as x, and y is 48 when x is 6

Find y when x is 2.

Solution:

In order to find y, we must first determine the constant of variation by multiplying  x and y.

k = xy

k = (48)(6)

k =288

288 = 2y

Divide both sides by 2 in order to determine y.

288/2 = 2y/2

y = 144

Final answer:

y = 144
