The vertices of triangle FGH are f(-2,1) G(1,3) and H((0,5) what are f'G'h' for a reflection over the y-axis? A. F'(-2,-1) G'(-1,-3) H(0,-5) B. F'(2,1) G(-1,3) H(0,5) C. F'(2,-1) G'(1,3) H'(0,-5) D'(-2,1) G'(1,3) H'(0,5)

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

Using this rule of reflection, we get

Similarly,

The vertices of F'G'H' are F'(2,1),G'(-1,3), H'(0,5). Therefore, the correct option is B.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
