Question
Which of the following are the correct coordinates when the point (-4,-6) is rotated 90° anticlockwise about the origin?
Solution
To rotate a point 90 degrees anticlockwise about the origin, you can use the following transformation rule: (x, y) becomes (-y, x).
So, for the point (-4,-6),
x becomes -(-6) = 6 y becomes -4
Therefore, the new coordinates after rotation are (6, -4).
