help please....
1:(-2, -1) is reflected over the y-axis. What are the coordinates of the image?
A:(2, -1)
B:(-2, 1)
C:(-1, -2)
D:(2, 1)
2:(2, -5) is reflected over the x-axis. What are the coordinates of the image?
A: (-2, -5)
B;(2, 5)
C:(-5, 2)
D:(-2, 5)
hope someone will help

thanks...
To find the coordinates of the reflected point, you need to understand how reflections work.
For question 1, the point (-2, -1) is being reflected over the y-axis. When a point is reflected over the y-axis, the x-coordinate changes its sign, while the y-coordinate remains the same.
So, to find the reflected point, you need to change the sign of the x-coordinate (-2) to positive, while keeping the y-coordinate (-1) the same.
Therefore, the reflected point is (2, -1). Hence, the answer is A: (2, -1).
For question 2, the point (2, -5) is being reflected over the x-axis. When a point is reflected over the x-axis, the y-coordinate changes its sign, while the x-coordinate remains the same.
So, to find the reflected point, you need to change the sign of the y-coordinate (-5) to positive, while keeping the x-coordinate (2) the same.
Therefore, the reflected point is (2, 5). Hence, the answer is B: (2, 5).
Make sure to always double-check your work by visualizing the reflection on a coordinate plane to confirm the accuracy of your answer.
