Do you guys know how to solve this?

B. y=x+7

Step-by-step explanation:

When x is 0, your y is 7. So your y-intercept (or b) is 7.

Each month adds on 1 pound, so instead of putting 1x, you just put x.

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

answer: 1, 3 and 5 are correct
