### Course description

This course explores the twin pillars of algebraic thinking—equations and graphs. With these two tools, we'll unpack algebra's big ideas and develop a powerful perspective to solve its essential problems. By the end of this course, you'll understand graphs and their relationship to the equations they represent, enabling you to answer questions involving equations even when it's impossible to solve them by hand. Though a familiarity with solving equations is helpful, we'll start with a review of the basics and build on them throughout the course. When you finish, you'll be ready to conquer a wide range of algebraic techniques in Algebra 1.

### Topics covered

- Algebraic Expressions
- Coordinate Plane
- Equations
- Graphs
- Linear Equations
- Ordered Pairs
- Rates
- Simplifying
- Systems of Equations
