A direct variation function contains the points (2, 14) and (4, 28). Which equation represents the function?

y = y equals StartFraction x Over 14 squared EndFraction.
y = y equals StartFraction x Over 7 squared EndFraction.
y = 7x
y = 14x

Answer 1

y = 7x

it is simple : x times how much is y ?

2 × ? = 14

? = 7

control

4 × ? = 28

? = 7

identical, so it is correct, and y = 7x is the answer.
