Answer 1

When reflecting a point over the y-axis, the x-coordinate of the point changes sign, while the y-coordinate remains the same.

Given the points:

• \( A(1, -10) \)
• \( B(-10, 3) \)

To find their reflections:

1. For point \( A(1, -10) \):

   • Reflect over the y-axis: \( A'(-1, -10) \)

2. For point \( B(-10, 3) \):

   • Reflect over the y-axis: \( B'(10, 3) \)

Thus, the reflected points are:

\[ A'(-1, -10) \]

\[ B'(10, 3) \]
