It's A.
It's A
First, find the rule for a rotation of 180°, which is
R(O,180): (x,y)->(-x,-y)
so
(3,-5) -> (-(3),-(-5))
can you take it from here?

It should help you get the right answer.
To find the coordinates of the image of point R(3,-5) rotated 180° about the origin, you can use the following steps:
1. The origin, (0,0), is the center of rotation. Since we are rotating 180°, the image will be on the opposite side of the origin.
2. The x-coordinate of the image will be the opposite (negative) of the original y-coordinate, and the y-coordinate of the image will be the opposite (negative) of the original x-coordinate.
Applying these steps, we can find the image of point R(3,-5) as follows:
x-coordinate of the image = -1 * (-5) = 5
y-coordinate of the image = -1 * 3 = -3
Therefore, the coordinates of the image of point R(3,-5) rotated 180° about the origin are (5,-3). Hence, option C)(5,3) is the correct answer.
