Question

an algebraic rule of (x, y) → (-x, y) is reflection across the choose your answer.. choose your answer.. y - axis x - axis previous

Explanation:

In a coordinate - plane, when we change the sign of the x - coordinate and keep the y - coordinate the same for a point (x, y) to get (-x, y), we are reflecting the point across the y - axis. Reflecting across the x - axis changes the sign of the y - coordinate (x, y)→(x, -y).

Answer:

y - axis
