1. Warm-Up #21 (Tuesday, 10/20)
Given 3x + y = 3, if y = 3 find the value of x
4x + 2x – 2 = 42 solve for x

2. Homework (Tuesday, 10/20)

3. Lesson 3.02 Transformations

4. Transformations Example: (x, y) ↦ (x+3, y) (5, 12) ↦ (5+3, 12)
A transformation transforms, or maps, the original point to another point. Transformation uses a combination of operations (+, −, ÷, x)
notation: ↦ “maps to”
Example: (x, y) ↦ (x+3, y)
(5, 12) ↦ (5+3, 12)
( 8, 12) new point

5. Practice Problem
(3, -2) (4, 1) (-5, -2) (-7, 0)
(x, y) ↦ (x, y - 2 )
