Question
A point A(-4, 1), reflect A over the x- axis and then translate the resulting point 3 units left. Write the coordinate of the new point, A′.
- A’ (-4, -1)
- A’ (-4, 1)
- A’ (-7, -1)
- A’ (7, -1)
Hint:
A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.
The correct answer is: A’ (-7, -1)
A point A(-4, 1), reflect A over the x- axis, we get the point (-4,-1) and then when it is translated 3 units left, we get A'(-7,-1).
Hence, the correct option is A.
A point can be reflected about any of the two axes or about any line.
