To find the coordinates of point I' after reflecting point I over the line \( x = 1 \), we follow these steps:

  1. Let's denote the coordinates of point I as \( (x, y) \).

  2. The reflection of a point \( (x, y) \) over the line \( x = 1 \) can be found using the following formula:

    \[ x' = 2 \times \text{line_x} - x \] where \(\text{line_x}\) is the x-coordinate of the line of reflection. In this case, \(\text{line_x} = 1\).

  3. The y-coordinate remains the same, so \( y' = y \).

Now, we need to evaluate the reflection for each of the given points to find point I's coordinates:

  1. For point (-5, 2):

    \[ x' = 2 \times 1 - (-5) = 2 + 5 = 7 \] So, I' = (7, 2).

  2. For point (5, 0):

    \[ x' = 2 \times 1 - 5 = 2 - 5 = -3 \] So, I' = (-3, 0).

  3. For point (-3, 2):

    \[ x' = 2 \times 1 - (-3) = 2 + 3 = 5 \] So, I' = (5, 2).

  4. For point (-2, 5):

    \[ x' = 2 \times 1 - (-2) = 2 + 2 = 4 \] So, I' = (4, 5).

Since none of the reflections provided give us a final point that matches those listed, it appears your point I wasn't specified. However, we calculate reflection for each and none reflected generate the points provided initially.

If you meant the original coordinates I are one of those listed, please specify which one so the exact reflection over x=1 can be reported back.

Given that point \( I = (5, 2) \), we will reflect it over the line \( x = 1 \).

  1. Identify the coordinates of point I:

    \[ I = (5, 2) \]

  2. Use the reflection formula for the line \( x = 1 \):

    \[ x' = 2 \times 1 - x = 2 - 5 = -3 \]

    The y-coordinate remains unchanged:

    \[ y' = y = 2 \]

  3. Putting it together, the coordinates of the reflected point \( I' \) are:

    \[ I' = (-3, 2) \]

Thus, the coordinates of point \( I' \) after reflection over the line \( x = 1 \) are:

\[ \boxed{(-3, 2)} \]

This point \( (-3, 2) \) is not listed in your original options of coordinates \((-5, 2), (5, 0), (-3, 2), (-2, 5)\) but matches with \( (-3, 2) \).
