Question

please help really simpleeeeeeeeeeeee plsssss help really simple i am just checking my awnser pease tell me what would the coordinates be after the triangle P' Q' R' is reflect over the y-axis would be the coordanites are P'(1, 0), Q'(0, −1), and R'(−2, −1).

Answer 1

Answer:

P(-1, 0); Q(0, -1); R(2, -1).

Step-by-step explanation:

When you reflect coordinates over the y-axis, the y-coordinates do not change, while the signs of the x-coordinates are flipped. You can see the example attached!

And so, after reflecting P'(1, 0), you would get P(-1, 0) because the sign of the x-value is flipped and the y-value does not change.

Q'(0, -1) becomes Q(0, -1) because 0 is neither negative nor positive, and the y-value does not change.

R'(-2, -1) becomes R(2, -1) because the sign of the x-value is flipped to positive and the y-value does not change.

Hope this helps!
