Answer 5

Triangle PQR has vertices P(-1,3), Q(1,2), and R(-2,-1). When Triangle PQR is reflected over the line y=-2, what are the coordinates of P?

Answer 6

A) (-1,-3)
B) (-1,-7)
C) (-2,-2)
D) (-3,-3)

Answer 7

B

Answer 8

how?

Answer 9

P(-1,-7)

Answer 10

You should draw it, that'll make it a lot clearer.

Answer 11

because when you reflect it over the line you take the distance between the point and the line which would be 5 for Y and it wouldn't change for X because you are only change the Y. since it is 5 for Y you just go down 5 points from the line which would mean Y=-7 and then keep the same X which would mean X=-1 so (-1,-7)

Answer 12

Thankyou.

Answer 13

(3 + y)/2 = -2 -> y is -7

Answer 14

\[\sqrt{4789}\]
