Question

If y varies directly as x and y=32 when x=4. find the constant of variation​

Answer 1

k = 8

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 the condition y = 32 when x = 4, then

32 = 4k ( divide both sides by 4 )

8 = k
