Which relationship between x and y in the equation shows a proportional relationship? a. y=x−2 b. y=4x+2 c. y=8x d. y= x 2 +2

A proportional relationship with a linear equation is a special kind of relationship  where the line always goes through (0,0) on the coordinate plane.

y = mx is the equation for a proportional relationship because c = 0, while y = mx + c isn't.

C is the only one without a constant, since it is in the form of y = mx. So, C is the only possible answer here.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
