The image of A(3, 4) under R₉₀° is (-4, 3)
What is rotation?
Rotation is when an object is turned clockwise or counter clockwise around a given point.
In other words, rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point. The fixed point is called the centre of rotation .
Rotation usually occur around a point.
Therefore, When rotating a point 90 degrees counter clockwise about the origin our point A(x, y) becomes A'(-y, x).
In other words, switch x and y and make y negative.
The image is rotating anticlockwise 90 degrees. Therefore, the new image coordinates are as follows:
(3, 4) → (-4, 3)
