# Algebra I – Semester 1

## Algebra I – Semester 1

## Recommended Grade Level: 9 - 12

This course provides an introduction to High School Algebra. Student learns about the history of algebra and the various mathematicians who have contributed to this field. The course introduces the student to variables and algebraic expressions and properties. Student learns to evaluate variable expressions and equations and solving linear equations. They learn about one-variable inequalities and understand how to graph them. The course then delves into two-variable linear equations and two-variable inequalities. Students study the Slope-intercept form and learn how to write and graph slope-intercept equations. They explore the Point-slope form and the Standard form. The course teaches students how to graph two-variable inequalities and about Absolute Value equations and inequalities.
