Alrighty

3 cubes
if you stack them then you can cover, at most 3 faces

each cube has 6 faces
so 6*3=18
minus the 3 coverd is 18-3=15

so if the surfece area is equal to 15 of those faces ten
84=15 faces
divide by 15
84/15=area of 1 face

a cube has 6 faces to multiply by 6
84/15 times 6=504/15=168/5=33.6 square inches is the surface area of one of grogg's cubes

Answer: B) Linear; it can be written as y = -3x-6

We subtract 6 from both sides to go from the original equation to -3x-6 = y

Then we flip both sides to end up with y = -3x-6

This is in slope intercept form y = mx+b with m = -3 as the slope and b = -6 as the y intercept.
