Question

The constant of proportionality in the equation y = 1 half x is _______.

  1. x
  2. y
  3. 1 half
  4. 2

hintHint:

Constant of proportionality is the constant value of the ratio between two proportional quantities.

The correct answer is: 1 half


    To check the constant of proportionality,we use k = y/x ,where k is the constant ratio of y values to corresponding x values.
    Here , y = 1/2 x
    Or, y/x = 1/2 , where k = 1/2 .
    Therefore, the constant of proportionality in the equation y = 1/2 x is 1/2 .
    Hence, the correct option is (a).

    When a ratio is written as a fraction, the constant of proportionality is the number gotten by dividing the denominator by the numerator.
