Andrea has to find a third point, C
, to form a triangle on the coordinate plane shown. She is told the coordinates of its reflection point, C′
, across the x
-axis are (2,−2)
. What are the coordinates of point C
?
(1 point)
To find the coordinates C, we can use the fact that the reflection across the x-axis changes the sign of the y-coordinate.
Since the reflection point C' has coordinates (2, -2), the y-coordinate of C is the negative of -2, which is 2.
Therefore, the coordinates of point C are (2, 2).
