Question

This graph shows a proportional relationship. What is the constant of proportionality?

Answer 1

The constant of proportionality is 12

Constant of proportionality

The slope of the graph is equivalent to the constant of proportionality

The formula for calculating the slope is given as:

$m =\frac{y_2-y_1}{x_2-x_1}$

Using the coordinate points (5, 60) and (3, 36)

Substitute the given parameters into the equation:

$m =\frac{36-60}{3-5}\\m =\frac{24}{2}\\ m = 12$

Hence the constant of proportionality is 12
