The coordinates of the image of line segment RT are R’(-2, -4) and T’(4, 4). The image was produced by a dilation with a scale factor of ½ centered at the origin. What are the coordinates of the endpoints

The coordinates of the image of line segment RT are R’(-2, -4) and T’(4, 4). The image was produced by a dilation with a scale factor of ½ centered at the origin. What are the coordinates of the endpoints of the pre-image?

thank you in advanced :)

Answer:

R(-4,-8) and T(-8,8)

Explanation:

  • Dilation multiplies or divides. Since it is .5 dilation, the pre-image has greater points.
  • This multiplying each end point by 2 gives us our pre-image values.
