1. Day 33 Reflection of graphs about the x- and y-axis

2. Introduction

3. Vocabulary:
Reflection A figure is said to have undergone a reflection if its distance from a central line is equal to that of its image from that particular line and the two images are laterally inverted. The central line is called the mirror line.
This can be done in the notebooks or on vocabulary cards. Whatever system you use 
