Question

The quantity, y, varies directly as x. When y=10 x=6

Answer 1

Answer:

y = $\frac{5}{3}$ x

Step-by-step explanation:

given y varies directly as x, the the equation relating them is

y = kx ← k is the constant of variation

to find k use the given condition y = 10 when x = 6, hence

k = $\frac{y}{x}$ = $\frac{10}{6}$ = $\frac{5}{3}$

y = $\frac{5}{3}$ x ← is the equation
