A is the answer Bc I did this before and my teacher said I did an excellent job!
Answer: 2
Step-by-step explanation:
m = y2 - y1 / x2- x1
where slope is m,
so in this case it would be
m= 1-(-1) / 3-2
m=2/1
m=2
Note that you can do it either way
-3(x-14)+9x=6x+24
-3x+42+9x=6x+24
-3x+9x-6x=-24-42
0=-18
38= Sum
2= GCF of 18 and 20
