Point A(-2, -10) is reflected over the x axis. Write coordinates of A
That is the exact question I have on my homework!
When a point is reflected over the x-axis, the y-coordinate is negated while the x-coordinate stays the same.
So, to find the coordinates of A after reflecting it over the x-axis, we negate the y-coordinate of A.
Given that A has coordinates (-2, -10), after reflecting it over the x-axis, the coordinates of A would be (-2, 10).
To reflect a point over the x-axis, you need to change the sign of its y-coordinate while keeping the x-coordinate unchanged.
Given that point A is (-2, -10), to find the coordinates of the reflected point, follow these steps:
1. Change the sign of the y-coordinate: Since the y-coordinate of point A is -10, changing the sign gives us +10.
2. Keep the x-coordinate unchanged: The x-coordinate of point A is -2, and it remains the same after reflecting.
Therefore, the coordinates of the reflected point A are (-2, 10).
such a reflection takes (x,y)→(x,-y)
