Front

Linear System

Back

A collection of one or more linear equations involving the same set of variables.

Front

Intersecting Lines

Back

Lines that cross each other at exactly one point.

Front

Coinciding Lines

Back

Lines that lie exactly on top of each other, having infinitely many points in common.

Front

Parallel Lines

Back

Lines in a plane that never meet; they have the same slope but different y-intercepts.

Front

Linear Regression

Back

A statistical method for modeling the relationship between a dependent variable and one or more independent variables.

Front

Solving Linear Systems

Back

The process of finding the values of variables that satisfy all equations in the system.

Front

Classifying Linear Systems

Back

Determining whether a system of equations is independent, dependent, or inconsistent.

Front

Independent Linear Systems

Back

Systems with exactly one solution.

Front

Dependent Linear Systems

Back

Systems with infinitely many solutions.

Front

Inconsistent Linear Systems

Back

Systems with no solution.
