Answer:
B
Step-by-step explanation:
Because
=4.5Y+15
We move all terms to the left:
-(4.5Y+15)=0
We get rid of parentheses
-4.5Y-15=0
We move all terms containing Y to the left, all other terms to the right
-4.5Y=15
Y=15/-4.5
Y=-3+1/3
18
The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The factors of 18 are 1, 2, 3, 6, 9, 18
The common factors are 1, 2, 3, 6, 9, 18
The greatest common factor = 18
-0.25 or -1/4
Remember slope is : change in y's over change in X's
