Question

The graphs below show measurements from cubes with different side lengths.







Which pairs of variables have a linear relationship? Select two options.

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

Can you add the graphs please?

Answer 2

I couldn't find the graphs anywhere

With that said, you're looking for a linear relationship between the two variables

If side length is x, then perimeter of that face is 4x, which is linear wrt x

I'll let the OP figure out the other one if they come back
