Given that x and y vary directly, write the equation relating x and y if x = 3 when y = 24. a) y = 8x b) xy = 8 c) y = 8 x d) y = x 8 4)

A

given that y varies directly as x, then the relationship is

y = kx ← k is the constant of variation

To find k use the given condition x = 3 when y = 24

y = kx ⇒ k = = = 8

y = 8x

50-60=10
