graph of a linear inequality in two variables how does it differ from the graph of a linear inequality in one variable?

Question

whats the difference between a graph of a linear inequality in two variables and the graph of a linear inequality in one variable?

 

Answer 1

In one variable, there is a value on the line marked with an open or closed circle, and the values which solve the inequality are shaded. In two variables, a solid or dashed line is graphed in a plane, and the regions of the plane where there are points which solve the inequality are shaded.
