Answer:
y = 7x
Step-by-step explanation:
Given that y varies directly as x the the equation relating them is
y = kx ← k is the constant of variation
To find k use the points given
k = [tex]\frac{y}{x}[/tex] = [tex]\frac{14}{2}[/tex] = [tex]\frac{28}{4}[/tex] = 7
y = 7x ← equation representing the function
