Question

find the coordinates of the vertices of the triangle after a reflection across the line y = -1 and then across the line x = -2​

Answer 1

Answer: A) N'=(-2, 2) M'=(-1, 0) L'=(-5, -2)

Explanation:

N = (-2, -4) M = (-3, -2) L = (1, 0)

Reflection over y = -1

N' = (-2, 2) M' = (-3, 0) L' = (1, -2)

Reflection over x = -2

N'' = (-2, 2) M'' = (-1, 0) L'' = (-5, -2)
