Answer: D. (-4, -2)
<u>Step-by-step explanation:</u>
Rotating 180° about the origin means the signs for the x- and y-values are opposite.
(x, y) → (-x, -y)
(4, 2) → (-4, -2)
Okay so the first thing you need to do is move the all the variables to one side of the equal sign
The answer would be 108. 108:45 can be simplified to 12:5.
