The image of the point (4,-2) under a rotation 180 degrees about the origin is A. (−2,−4) B. (−2,4) C. (−4,−2) D. (−4,2)

D

Step-by-step explanation:

(4,-2) is located in the fourth quadrant and to think about it, if you rotates it 90 degrees clockwise it will be located in the third quadrant and another 90 degrees it will be located in the second quadrant. And the the second quadrant is the opposite of the fourth quadrant so you will have to find the opposite of the numbers. The opposite of 4 is -4 and the opposite of -2 is 2 so you will have the new coordinates (-4,2)

rotating (4,-2) 180 degrees will be (-4,2)

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
