Which statement describes what happens when (4, 6) is reflected across the y-axis? Select all that apply:

A) The y-coordinate of the reflection is -6.
B) The x-coordinate of the reflection is -4.
C) The reflection is in Quadrant II.
D) The reflection is in Quadrant IV.

Answers

Answer: Actually the answer up there is wrong here is your answer:

The x -coordinate of the reflection is -4. and The reflection is in Quadrant II.

Step-by-step explanation: there you go have a great day.=D

The correct description for when (4, 6) is reflected across the y-axis,

⇒ The x-coordinate of the reflection is -4.

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

Point (4, 6) is reflected across the y-axis.

We know that;

The rule of reflection about the y - axis is,

⇒ (x, y) → (- x, y)

So, Point (4, 6) is reflected across the y-axis, the point is,

⇒ (4, 6) → (- 4, 6)

Thus, The correct statement is,

⇒ The x-coordinate of the reflection is -4.
