The quantities x and y are proportional X= 8, 16, 32
Y= 2, 4, 8
Find the constant of proportionally (r) in the equation y= rx
r=

Step-by-step explanation:

Given

The x and y values

Required

Determine the constant of proportionality

This is calculated from:

Pick any corresponding x and y values:

and

Substitute 8 for x and 2 for y in

Make r the subject

Pick another x and y values:

and

Hence, the constant of proportionality is 1/4
