Answer:

y=-y'

Step-by-step explanation:

Answer:

y=-y'

Step-by-step explanation:

The reflection is across the x-axis, so the sign of the y-coordinate changes. The algebraic expression to represent the new y-coordinate after a reflection across the x-axis given any initial y-coordinate, y, is -y.
