(See image below) The point A(-15) is rotated 270° clockwise about the origin. The coordinates of A' are?

Given:
A (-1,5) rotated 270 clockwise.
Find: A' coordinates
Sol:.
(x,y) Rotated by 270 become (y,-x).
A = (-1,5)
[tex]\begin{gathered} A=(-1,5) \\ A^{\prime}=(5,-(-1)) \\ A\text{'=(5,1)} \end{gathered}[/tex]
