Which of the following has a constant of proportionality of 2? y = 2x y = x + 2 2y = x y + 2 = 2x

Answer : y= 2x

When y is directly proportional to x then

y = kx where k is the constant of proportionality.

y = 2x , the value of k is 2. so 2 is the constant of proportionality.

y = x + 2, the equation is not in the form of y=kx

2y = x , so constant of proportionality k is

y + 2 = 2x , y = 2x -2 is not in the form of y=kx
