Question

The point A (3, 2) is rotated 270 counterclockwise about the origin and is then reflected over the y-axis. What is the ordered pair for point A

Answer 1

the point is A(3,2)

when we rotate a point (x, y) 270 degrees about the origin counterclockwise

then

(x, y ) becomes (y,-x)

so the point A will be (2, -3) after the rotation,

now we reflect it over y axis, x will replaced by -x

so the point A will be

(-2, -3)

thus, the answer is (-2, -3)
