Question

Explain how you can find the constant of proportionality from a graph representing a proportional relationship when it shows a point with an x-value of 1 and if it doesn’t show an x-value of 1.

Answer 1

For a proportional relationship, the constant is found dividing all values of y by each respective value of x.

What is a proportional relationship?

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

The constant can be represented as follows:

$k = \frac{y}{x}$

Hence the constant is found dividing all values of y by each respective value of x.
