Point A is the original point before rotating. Which point represents A prime after A (4, 1) is rotated 90 degrees counterclockwise
To rotate a point 90 degrees counterclockwise, we can use the following formulas:
x' = -y
y' = x
Using these formulas, we find A prime after rotating A (4, 1):
x' = -1
y' = 4
Therefore, A prime is (-1, 4).
