2. Lesson 57 Warm-Up:
Use the figure below to answer #1 & #2.
1) Name one pair of alternate interior angles.
2) If the m a is 120 degrees, what is the
measure of f?
a b
d c
e f
h g
3) Simplify: x9 y
x8 y
4) Simplify: 2x2 - 3x - x2 + 5
5) Graph y = x - 2 on a coordinate plane.

3. Lesson 57:
FYI...Remember:
--multiplying & the "bases" are the same - add the exponents
--dividing & the "bases" are the same - subtract the exponents
