State the slope and y-intercept of the graph of y = 1/5x – 7.

The slope is 1/5 and the y-intercept is -7

Step-by-step explanation:

In point-slope form (y = mx + b), m is the slope and b is the y-intercept.

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: .64
