To rotate a point 90° counterclockwise around the origin, we can swap the x and y coordinates of the point and negate the new y coordinate.
So, applying this to point B(-1,-5):
- Swap the x and y coordinates to get (y, x) = (-1, -5)
- Negate the new y coordinate to get B' = (-5, 1)
Therefore, the coordinates of the resulting point, B', are (-5, 1).
So, applying this to point B(-1,-5):
- Swap the x and y coordinates to get (y, x) = (-1, -5)
- Negate the new y coordinate to get B' = (-5, 1)
Therefore, the coordinates of the resulting point, B', are (-5, 1).
