Respuesta :
it could be 2.2 because every 5 you get 2 so it would be 10 and 4 so when y=6 then x should be 2.2.
Answer:
y = 15
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportionality.
To find k use the condition y = 5 when x = 2
k = [tex]\frac{y}{x}[/tex] = [tex]\frac{5}{2}[/tex] = 2.5, thus
y = 2.5x ← equation of proportionality
When x = 6, then
y = 2.5 × 6 = 15
