Question

how do the values of x and y coordinates change when you reflect across the y axis

Answer 1

Answer:

(x,y) to (-x,y)

Explanation:

When a point (x,y) is reflected across the y-axis​, we have the transformation rule below:

$(x,y)\to(-x,y)$

What this means is that:

0. The value of the x-coordinate changes to its opposite sign.

,

1. The value of the y-coordinate remains the same.
