Aline passes through the points (-1,4) and (2,-2) what is the equation of this line

Finding the slope, you get [4-(-2)]/[-1-2]=6/-3 = -2

Plugging (2,-2) and -2 into the formula y=mx+b, you get that -2=-4+b.

Therefore, b=2, making the equation y = -2x+2

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
