Question

Marissa has a photograph that measures 2 in. by 4 in. She has mounted the picture on a mat so that there is a border that measures 1 in. around the picture. The graph shows a representation of the photograph and the mat on the coordinate grid. Marissa has decided to dilate the picture and the mat by a scale factor of 2. Draw the new image for the picture and mat on the coordinate grid.

Answer 1

To get the new image of the picture and mat on the coordinate grid, you need to dilate the original dimensions by a scale factor of 2.

Step-by-step explanation:

To draw the new image of the picture and mat, we need to dilate the original dimensions by a scale factor of 2. The original picture measures 2 in. by 4 in., so we multiply each side by 2 to find the dimensions of the new image.

2 in. x 2 = 4 in.

4 in. x 2 = 8 in.

Therefore, the new image of the picture and mat will measure 4 in. by 8 in. on the coordinate grid.

Answer 2

Step-by-step explanation:

The initial image of the photo is 2 in by 4 in. The mat is 4 in by 6 in.

The new image is dilated by a scale of 2. So we double the dimensions. The new photo is 4 in by 8 in. The new mat is 8 in by 12 in.
