When a point is reflected across the x-axis, the x-coordinate remains the same, while the y-coordinate changes sign.
Let's apply this to the points of triangle ABC:
-
For point A(−4,−1), the reflection A′ will be:
A′(−4, 1) -
For point B(−5,−2), the reflection B′ will be:
B′(−5, 2) -
For point C(−10,−1), the reflection C′ will be:
C′(−10, 1)
So, the coordinates of the reflected points are:
- A′(−4, 1)
- B′(−5, 2)
- C′(−10, 1)
Therefore, the correct response is:
A′(−4,1), B′(−5,2), and C′(−10,1)
