Question
The constant of proportionality in the equation y = x is _______.
- x
- y
- 2
Hint:
Constant of proportionality is the constant value of the ratio between two proportional quantities.
The correct answer is:
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.
