Suppose that y varies directly with x and y=5 when x=6. what is y when x=5? be sure to simplify your answer.

y =

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 5 when x = 6

k = = , thus

y = x ← equation of variation

When x = 5, then

y = × 5 =
