The option representing the transformation of a point under rotation about an arbitrary point is indeed parameterized equations with rotation angles. This is because a rotation of a point in a coordinate system involves a series of trigonometric calculations based on angles, ensuring that the point’s distance from the center of rotation remains the same while changing its position according to the specified angle.

When you rotate a point, you typically use formulas derived from the angle of rotation. For example, if you want to rotate a point (x, y) around a center of rotation (h, k) by an angle θ, you would use the following parameterized equations:

  • x' = h + (x - h) * cos(θ) - (y - k) * sin(θ)

  • y' = k + (x - h) * sin(θ) + (y - k) * cos(θ)

These equations demonstrate how the coordinates of the point change based on the angle of rotation and the center of rotation, making this option the correct choice.

In contrast, linear equations with one variable do not capture the complexity of rotational transformations as they typically only relate to changes in a single dimension. Simple addition of constants to coordinates would not account for
