Question

1. Explain how you can use the algebraic representation to determine the new coordinates of a point. 2. Describe how you know if the image is reduction or enlargment of the pre-image.

Answer 1

Answer: for number 1, Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.

Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.

And for number 2, if the image is smaller than the pre image, it is an enlargement. If the image is larger than the pre image, it is a reduction. :)

Step-by-step explanation:

In a two-dimensional plane, coordinates of a point define its exact location. The coordinate plane has two axes that are perpendicular to each other which are known as the x and y axis.

To find out the coordinates of a point in the coordinate system, follow the following procedure.

Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.

Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.

The x-coordinate and the y-coordinate determine the new coordinates of a point.
