Question

1. a(-3, 5) is rotated to a(3, -5). describe the rotation.

Explanation:

When a point $(x,y)$ is rotated 180 - degrees about the origin, the new coordinates $(x',y')$ are given by $x'=-x$ and $y' = -y$. For point $A(-3,5)$, when rotated 180 - degrees about the origin, we get $A'( -(-3),-5)=(3,-5)$.

Answer:

180 - degree rotation about the origin.
