Exploring Reflections Over Horizontal and Vertical Lines

The video tutorial explains how to perform reflections on a coordinate grid when the line of reflection is not an axis. It covers graphing horizontal and vertical lines, specifically y = -5 and x = 2, and demonstrates how to reflect points over these lines. The tutorial emphasizes labeling new points with primes and provides tips for accurately connecting points to form shapes.

What is the line of reflection if it is not the x-axis or y-axis?

• x = 2

• y = -5

• x = 0

• y = 0
