Identify values that satisfy a linear inequality and interpret the solution using multiple representations.
[i]Answer these open ended questions on your own or with others to form deeper math connections.[/i]
Drag the moveable point across the number line to test which integer values are solutions to the inequality. Try again with another inequality. Sometimes there is an open end point in the solution graph, and sometimes there is a closed point. What determines whether the end point is open or closed?
Suppose you are given the inequality 23>9+7x. Describe all of the points (values for x) that would keep the right side lighter than the left side.
