Question

Please help me out!!!!!!!!!!!!!!!!

Answer 1

y = 0.5x

Explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 1, y = 0.5, then

k =
`(y)/(x)` =
`(0.5)/(1)` = 0.5, hence

y = 0.5x ← equation of variation
