Question

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

Answer 1

The correct answer is A. Because if you substitute the x and y you will get the same outcome. y=8x substitute and you get 24= 8(3) and then multiply and you get 24 = 24
