Triangle XYZ is shown on the coordinate plane below: If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?

Step-by-step explanation:

Triangle XYZ has been reflected across a line y = 1,

Therefore, line y = 1 will work like a mirror and all the distance of the points of the points from this line will be equal after the reflection about this line.

Distance of X from this line = 2 units

After reflection distance of X' from the line of reflection will be 2 units in opposite side.

Therefore, coordinates of X' will be (3, 3)

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

answer:   c ?
