If the reflection is on the y axis, y - coordinate remains the same and the sign of x coordinate changes.
The reflection point of A(2, 5) in the y axis is (-2, 5). Therefore, k = -2 and m = 5. k + m = 3
The reflection point of A(2, 5) in the y axis is (k, m). The value of k + m is ___.
The reflection of the point A(2, 5) about X = 0 is (k, m). The value of k+m is ___.
