# Introductory Algebra I

Educator Edition

 Contributor Portland Community College Course MTH 60, Introductory Algebra - First Term. Introduces algebraic concepts and processes with a focus on linear equations and inequalities in one and two variables. Emphasizes applications, graphs, formulas, and proper mathematical notation throughout the course. Textbook ORCCA (Open Resources for Community College Algebra) by Cary, Jordan, and Yao Prerequisites Intended for students who have passed the Basic Math (Arithmetic) course

Edfinity is a full-featured homework system. Use this problem series as-is, or mix-and-match with other series or your own problems as desired. Edfinity gives you complete control over the every aspect of students' online assessment experience.

## Intended Outcomes

Upon completion of the course students should be able to:

• Simplify and evaluate algebraic expressions.
• Represent a quantity with an algebraic expression for a given situation.
• Use a variable to represent an unknown in a linear problem, create a linear equation or inequality that represents the situation, and find the solution to the problem using algebra.
• Distinguish linear and non-linear relationships between quantities represented by two variables when given a graph, table, verbal description or algebraic formula.
• Identify and interpret the rate of change in linear data, construct a model and use the model to make predictions.

This problem series includes WeBWorK-enhanced problems. WeBWorK problems are highly sophisticated, supporting the representation and manipulation of mathematical objects such as vectors, points, matrices, intervals, and complex numbers, with customizable answer checkers. Students are encouraged to make multiple attempts until they succeed, and given immediate feedback on correctness.

Edfinity provides full access to the WeBWorK Open Public Library (OPL), a collection of over 20,000 rich, interactive problems across a wide range of math and science subjects, including college algebra, discrete mathematics, probability and statistics, single and multivariable calculus, differential equations, linear algebra and complex analysis.
