Today, students continued to study the linear inequality, solving one variable inequality, three ways to represent inequality solution, inequality notation, interval notation, and number line; For two-variable inequality, graphing is used to present the solutions because the solution is zone bordered by a straight line from the inequality. The method of drawing the two-variable inequality and inequality system was introduced in the class.

Here is the homework for today’s class
