Question

If you reflect triangle MOV across the y-axis, what is the coordinate of V' in the image?

(–1, 1)
(1, –1)
(1, 1)
(–1, –1)

Answer 1

Answer: the answerr is B

Answer 2

V is at (-1,-1)

by reflecting it across the y axis its x coordinate gets inverted:

V'=(-1*-1,-1)=(1,-1)

so the second option is the correct one
