### What is the formula for reflection?

What is the formula to find reflection? Performing reflections The line of reflection is usually given in the form y = m x + b y = mx + b y=mx+by, equals, m, x, plus, b. How do I draw the line of reflection? Each point in the starting figure is the same perpendicular distance from the line of reflection as its corresponding point in the image.

Reflection: flips a figure over a line (line of reflection) creates a mirror image. Each preimage vertex is the same distance from the reflection line as the vertices in the image. Reflection across y axis notes: Reflection across y axis: horizontal reflection (flips across) Reflection over y axis: y coordinates stay the same. and
