What is the solution to the system of equation graphed below

y=-x-1
y=x+1

0,1
-1,0
1,0
0,-1

y = -x-1

x+1 = -x-1 replace y with x+1

x+x = -1-1

2x = -2

x = -2/2

x = -1

If x = -1, then y is

y = x+1

y = -1+1

y = 0

So x = -1 and y = 0 pair up together to get (x,y) = (-1,0)

Choice B

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
