<h3>Key Concepts for Reflections:</h3>

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)
