-1 - (-7) = 6
5 - (-1) = 6
11 - 5 = 6
The common difference is 6.
If you add 6 to a term, you get the next term.

Answer:
-7g+13
Step-by-step explanation:
b) because combining like terms results in:
g-8g=7g
and
15-2= 13
A will be 7 x 5
B will be 10x10
The answer is B because the slope is always the one multiplying the x and the 1 is negative because the equation is y-y1=m(x-x1)
