Key Concepts
An equation that can be written
An equation that can be written in the form ax + by + c = 0, where a, b, and c are real numbers, and a and b are not both zero. Examples include 2x +
Any linear equation in two variables
Any linear equation in two variables can be expressed in this form where 'a' is the coefficient of x, 'b' is the coefficient of y, and 'c' is the cons
A solution to a linear equation
A solution to a linear equation in two variables is an ordered pair (x, y) where x and y are values that satisfy the equation when substituted. For 2x
Unlike linear equations in one variable
Unlike linear equations in one variable that have unique solutions, linear equations in two variables have infinitely many solutions. For any equation
