Question

On a coordinate plane, triangle P Q R has points (3, 0), (1, negative 2), (4, negative 2). Triangle PQR is reflected over the line y = x. What is the coordinate of the image point R’? R’(2, 4) R’(–2, –4) R’(2, –4) R’(–2, 4)

Answer 1

R'(- 2, 4 )

Explanation:

I got it right on edg

Answer 2

R'(- 2, 4 )

Explanation:

Under a reflection in the line y = x

a point (x, y ) → (y, x ) , thus

R(4, - 2 ) → R'(- 2, 4 )
