pls tell fast​

Answer 1

Answer:

question is (-1/2,3),(-5,6),(-8,8)

explanation

$x1 = - 1 \2 \\ x2 = - 5 \\ x3 = - 8 \\ y1 = 3 \\ y2 = 6 \\ y3 = 8 \\ x1 \binom{}{y3 - y2} + x2 \binom{}{y3 - y1} + x3 \binom{}{y2 - y1} \\ - 1 \2 \binom{}{8 - 6 } + - 5 \binom{}{8 - 3} + - 8 \binom{}{6 - 3 } \\ - 1 \2 \times 2 - 5 \times 5 - 8 \times 3 \\ - 1 - 25 - 24 \\ - 25 - 25 \\ - 50$
