What is the rule for a 180 degree rotation?

• (-y, -x)

• (y, -x)

• (-x, -y)

• (-y, x)

Answer explanation

A 180 degree rotation moves a figure around two whole quadrants (half a circle across the coordinate plane).
This results in the signs of both the x and y value being "flipped" (opposite) from what it started as.
$\left(x,y\right)\longrightarrow\left(-x,-y\right)$
