Which algebraic representation of a transformation on a coordinate grid does NOT preserve congruence? A. ( x, y) -> ( x + 6, y + 6)
B. (x, y) -> (-x, y)
C. (x, y) -> (6x, 6y)
D. (x, y) -> (-y, x)

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
