What is the equation of the line?

x = -9 also called undefined slope.

Step-by-step explanation:

And if the line is like this it is zero slope and the equation is the number that is passes through the y- intercept.

Hope this helps.

x = -9

x=-9

I hope this is good enough:

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

step-by-step explanation:

the answer is 128
