Question

This table represents a proportional relationship between x and y.

x 0.2 0.4 0.6 0.8
y 0.25 0.5 0.75 1.0
What is the constant of proportionality?

Enter your answer as a decimal in the box.

Answer 1

Explanation:

proportional relationship ca be represented with the formula : y=kx

You have to find k. With the values on the table, just replace them in the formula and find k.

First x=0.2 and y=0.25 => 0.25=k*0.2=> k=1.25

Then x=0.4 and y=0.5 => k=1.25

in the same logic you will continue with the last 2 values, and it als will be k=1.25
