Question

The table below shows measurements (in inches) from cubes with different side lengths.

Which pairs of variables have a linear relationship? Check all that apply.

side length and perimeter of 1 face
perimeter of 1 face and area of 1 face
surface area and volume
area of 1 face and surface area
side length and volume

Answer 1

Having the table would be helpful but off the bat we know that for a linear relationship

Output = k * input + b
Where k and b are constants

You should look for the choices where one variable changes at a constant rate as the other variable also increases/decreases at a constant rate
