Suppose y varies directly as x. To solve you will need to find the constant of the variation, write the equation so you can answer the question. If y = 4 when x = 2,
find y when x = 16.*

32

Step-by-step explanation:

Given, y varies directly as x. So, y=kx, where k is the constant of proportionality.

Given, x=2, y=4. plug in the values in the equation.

4=k*2

k=4/2

k=2

x=16

y=2*16

y=32
