Answer:
y = [tex]\frac{5}{3}[/tex] 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 = [tex]\frac{y}{x}[/tex] = [tex]\frac{10}{6}[/tex] = [tex]\frac{5}{3}[/tex]
y = [tex]\frac{5}{3}[/tex] x ← is the equation
