Key Concepts for Reflections:

• if (a, b) is reflected on the x-axis, the image is the point (a, -b)
• if (a, b) is reflected on the y-axis, the image is the point (-a, b)
• if (a, b) is reflected on the line y = x, the image is the point (b, a)
• if (a, b) is reflected on the line y = -x, the image is the point (-b, -a)

(5, -6) --> (-5, 6)

Hope this helps!!

I'd right the key concepts for future reference!
