Triangle RST is to be reflected across the y-axis.
What will be the vertices of the reflected triangle?
A. R'(5, 3), S'(4, 1), and T'(1,3)
B. R'(5, –3), S'(4, –1), and T'(1,–3)
C.R'(–5, 3), S'(–4, 1), and T'(–1,3)
D.R'(–5, –3), S'(–4, –1), and T'(–1,–3

Well first of all is the y axis the up and down line or the left to right line?

kayders1997 · Answer

If you know what line it is, it will make the process of choosing much easier, you wouldnt even need to draw a picture or anything

Okay I think I know it. Is it A?

kayders1997 · Answer

Yes because once you reflect it you will be in the positive quadrant so all x and y values have to be positive therefore it would be a

Does that make sense?
