Question

The values of x and y vary directly and one pair of values are given. Write an equation that relates x and y. x=1,y=0.5

Please help me!!

Answer 1

Answer: 0.5

Explanation:

Answer 2

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

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

y = 0.5x ← equation of variation
