Point A(4,−7)
is reflected in the x-axis. Identify the coordinates of its image after this reflection.(1 point)
The coordinates of A′
are (
,
).
The coordinates of A after reflecting in the x-axis would be (4, 7).
To reflect a point in the x-axis, we keep the x-coordinate the same and change the sign of the y-coordinate.
Given that A(4, -7) is reflected in the x-axis, the image A' will have the same x-coordinate as A (which is 4) and the y-coordinate will change sign to become positive.
So the coordinates of A' are (4, 7).
