Linear Inequality Graphing Solutions with Two Variables

When graphing an inequality, why make a dashed boundary line?

• to show the solutions on the boundary

• to break up the equal and not equal parts

• to show that the points on the line are not solutions

• to show that its an inequality not an equation
