Given:
The vertices of triangle FGH are F(-2,1), G(1,3) and H(0,5).
To find:
The vertices of F'G'H' for a reflection over the y-axis.
Solution:
If a figure is reflected over the y-axis, then
[tex](x,y)\to (-x,y)[/tex]
Using this rule of reflection, we get
[tex]F(-2,1)\to F'(-(-2),1)[/tex]
[tex]F(-2,1)\to F'(2,1)[/tex]
Similarly,
[tex]G(1,3)\to G'(-1,3)[/tex]
[tex]H(0,5)\to H'(0,5)[/tex]
The vertices of F'G'H' are F'(2,1),G'(-1,3), H'(0,5). Therefore, the correct option is B.
