A'(1, -4)
B'(3, 2)
C'(4. -2)
Explanation:
Given
Triangle ABC with coordinates
A(1, 4), B(3, -2), C(4, 2)
To find
Coordinates of the image A'B'C' after a reflection over the x-axis
Solution
Rule for reflection over x-axis is
R(x) = (x, y) → (x, -y)
The coordinates will change as follows
A(1, 4) → A'(1, -4)
B(3, -2) → B'(3, 2)
C(4, 2) → C'(4. -2)
