Question

Graph the image of rectangle rstu after a dilation with a scale factor of 4, centered at the origin

Answer 1

T' (4,8)

S' (4,-4)

R' (-4,-4)

U' (-4,8)

Explanation:

A dilation is an enlargement if the scale factor is greater than 1 and a reduction if it is less than 1. In this it is an enlargement so you multiply each coordinate by the scale factor which is 4. Since the coordinate for T is (1,2) you multiply 1x4 and 2x4 making the new coordinate (4,8). Since it is a new coordinate you add ' to the letter for the coordinate. Then you do that for the rest of the coordinates and graph it.
