Question

Start with the point B (-1, -4). Reflect the point through the y-axis. What are the new coordinates of the point B’? Now reflect the point through the x-axis. What are the new coordinates of the point B’’? What is the relationship between the original point B and B’’? Can you describe this in terms of one reflection?

Answer 2

Reflecting a point through the y-axis meaning it changes the sign(pos. or neg.) of its' x-coordinate.
So that means the point B' is now (1,-4).
Reflecting a point through the x-axis meaning it changes the sign(pos. or neg.) of its' y-coordinate.
So that means the point B'' in now (1, 4).
This point, B'', is now the reflection across the y=-x line of point B.
