Question

What are the resulting coordinates of triangle L′M′N′ after reflecting triangle LMN across the line y = x?Question options:A) L′ (1, 1), M′ (2, 4), N′ (4, 1)B) L′ (–1, –1), M′ (–4, –2), N′(–4, –1)C) L′ (1, –1), M′ (4,–2), N′ (1,–4)D) L′ (–1, 1), M′ (–4, 2), N′ (–1, 4)

Answer 1

The coordinates of the triangle LMN is,

L (1,-1) , M (2,-4) , N (4,-1).

Thus, the coordinates of the traingale L'M'N' is,

L' (-1,1) , M' (-4,2) , N ' (-1,4)

the graph will look like this,

The correct option is D.
