Graphing Linear Inequalities
y > 2x - 3 is to the right.
The inequality symbol affects if we shade above or below the line. All of the shaded area are solutions!
The symbol also affects if the line is dashed or solid. Dashed lines are not included in the solutions, but solid lines are included.

Graphing Inequalities in Slope-Intercept Form
The graph of is shown to the right.
Less than (<) means dashed line, shaded below.
Use the slope (2/3) and y-intercept (-4) to see how the inequality matches the graph.
