Write the coordinates of the vertices after a reflection across the line y = 2. p(-1, -4)=? q(4, -4)=? r(8, -1)=? s(3, -1)=?

P' =  (-1, 8)  (the x coordinate stays the same and the y coordinate =  (distance between -4 and 2)  + 2 =  6+2 = 8).

using the same  process:-

Q' = (4, 8)

R' =  (8, 5)

S' = (3, 5)

the first one, all those points on the line just make a strait line.

the answer is (-4,-4)

hope this ! : d
