Question

(TIME SENSITIVE PLEASE HELP) Use matrices to determine the coordinates of the vertices of the reflected figure. Then graph the pre-image and the image on the same coordinate grid.
(Pictures added!!!)

Answer 1

The matrix R represents the reflection matrix for the provided vertices, and graph A represents the pre-image and the image on the same coordinate grid.

What is the matrix?

It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.

We have vertices shown in the picture.

Form a matrix using the vertices:

$= \left[\begin{array}{ccc}-3&5&6\\7&3&-5\\\end{array}\right]$

To reflect over the x-axis, multiply by the reflection matrix:

$= \left[\begin{array}{ccc}1&0\\0&-1\\\end{array}\right]\left[\begin{array}{ccc}-3&5&6\\7&3&-5\\\end{array}\right]$

$\rm R= \left[\begin{array}{ccc}-3&5&6\\-7&-3&5\\\end{array}\right]$

The above matrix represent the reflection matrix.

Thus, the matrices R represents the reflection matrix for the provided vertices, and graph A represents the pre-image and the image on the same coordinate grid.
