3y-18
Pull out 3 (common factor):
3(y-6)
A) 3(y-6) is the correct answer
Fourth one i think (the way u typed the q is confusing)
The answer is C, your b in the equation is 4, and your slope is 1/2. Starting from four, you move up one and right two which means the slope is 1/2.
2 is Reflexive property
4 is (I don't remember the specific property of this)
