System of Equations and Inequalities
... A linear equation in two variables can be written in the form ax + by = k, where a, b, and k are constants, and a and b are not equal to 0. A pair of equations is called a system of linear equations because they involve solving more than one linear equation at once. A solution to a system of equ ...

GRAPHING LINEAR EQUATIONS IN TWO VARIABLES
... To graph a linear inequality with two variables it is probably easier and recommended to change it to slope intercept form. There are two important rules to remember when graphing a linear inequality. If the inequality sign is > or <, the line is dashed. If the inequality is ≥ or ≤ , then the line i ...
