Question

PLEASE HELP?????????? the vertices of a triangle are p(4,7), q(8,-1) and r(-9,6). what are the vertices of the image reflected across the x-axis?

Answer 1

just imagine it is a mirror image

Answer 2

so just put the coordinates in the same place but just on the other side of the x-axis

Answer 3

When you reflect across the x-axis, the x-coordinate will remain the same but the y coordinate will become negative y.

(A,B) will become (A,-B) when reflected about the x-axis.

Answer 4

so -4,7, -8,1, and 9,-6

Answer 5

oh wait

Answer 6

wait im confused was that right what i just put ^^ ?

Answer 7

No, the previous numbers are not correct.

Answer 8

The first number is the x-coordinate. It will remain the same.
The second number is the y-coordinate. It will change sign.

Answer 9

so (4,-7), (8,1), and (-9,6) ??? @ranga

Answer 10

The last one is (-9,-6).

Answer 11

yeah thats what i meant!! sorry

Answer 12

That is it.
When reflecting across x-axis, the x-coordinate will remain the same and the y-coordinate will change sign.
When reflecting across y-axis, the y-coordinate will remain the same and the x-coordinate will change sign.
When reflecting about the origin, both the x-coordinate and the y-coordinate will change sign.

Answer 13

thank you a bunch!!

Answer 14

You are welcome.
