The coordinate of rectangle ABCD are given. Find the coordinates of its image after a dilation with the scale factor of 2.
A (2,4) B (-3, -1) C (0,9) D (6,-4)
I DESPERATELY NEED HELP WITH THIS QUESTION IT ISN'T MULTIPLE CHOICE SOMEONE HELP PLEASE!!!!
dilation is from the origin, unless otherwise specified. So,
(x,y) --> (2x,2y)
The new coordinates are thus
A(4,8) B(-6,-2) C(0,18) D(12,-8)
However, the figure is not a rectangle.
