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.

The new size of the picture is and the new size of the mat is This is shown in attached images.

Given-

The size of the photograph is 2 by 4 in.

  Thus the new dimension of the Picture is,

        Thus the new dimension of the mat is,

Hence the new size of the picture is 4 by 8 and the new size of the mat is 6 by 10. This is shown in attached images.

For more about the scaling the graph follow the link below-

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.
