Question

given the initial point (x, y) what coordinate expression gives the new coordinates of the point after a across the y-axis?​

Answer 1

Answer:

Given any initial point (x, y), a reflection across the y-axis means the y-coordinate remains the same but the sign of the x-coordinate changes. Therefore, the coordinate expression that gives the coordinates of the point after a reflection across the y-axis is (-x, y).
