Question

Please help me. This is so confusing.

The vertices of a polygon are given as follows: P(-2,4), Q(4,2), R(4,0); S(-12,0); k = 0.5 Find the coordinates of the vertex P' of the image after a dilation having the given scale factor. Type your answers as a coordinate pair in this format: (x,y)

Answer 1

If the center of dilation is the origin, you can just multiply each coordinate by the scale factor to find the new values.

P' will be (-1, 2)

If the center of dilation isn't the origin, my answer is invalid.

Answer 2
