Introduction to linear equations
This is a lesson that teaches how to determine if an expression is a linear equation; and how to graph a linear equation.
Basic Concepts: Representing patterns in linear relations, Reading linear relation graphs, Solving linear equations by graphing, Identifying functions
Related Concepts: System of linear equations, Graphing linear inequalities in two variables, Graphing systems of linear inequalities
Lessons
Expression: A collection of numbers, variables, and signs, such as 3,3x+4,5x2+2,x−3,etc
Equations: A mathematical statement with an equal sign, such as y=2,y=3x−2,y=x,x=3,etc
Linear Equation: Ax + By = C (A, B & C are constants; x & y are variables)
All linear equations are functions except a vertical line such as x = 3.
Equations: A mathematical statement with an equal sign, such as y=2,y=3x−2,y=x,x=3,etc
Linear Equation: Ax + By = C (A, B & C are constants; x & y are variables)
All linear equations are functions except a vertical line such as x = 3.
