Answer:
A
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3 , then
7 = 3k ( divide both sides by 3 )
[tex]\frac{7}{3}[/tex] = k
y = [tex]\frac{7}{3}[/tex] x ← equation of variation
When x = 7 , then
y = [tex]\frac{7}{3}[/tex] × 7 = [tex]\frac{49}{3}[/tex]
