Vertex a in quadrilateral abcd lies at (-3, 2). if you rotate abcd 180° clockwise about the origin, what will be the coordinates of a′ of the rotated quadrilateral a′b′c′d′?
a.
(3, -2)
b.
(-3, 2)
c.
(-2, 3)
d.
(-3, -2)

i think it is 18

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
