What is the rule for reflecting over the Y axis?

- The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same. For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P’, the coordinates of P’ are (-5,4).

## How do you reflect a point over the y-axis?

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

## How do you reflect over Y?

The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.

## How do you reflect across Y?

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

## What does it mean to reflect over Y 1?

the line y=1 is a horizontal line passing through all. points with a y-coordinate of 1. the point (3,10) reflected in this line. the x-coordinate remains in the same position.

## Which transformation shows a reflection across the y-axis?

Another transformation that can be applied to a function is a reflection over the x– or y-axis. A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis.
