Two-Variable 2 Two-Variable Inequalities Worked Out After working with and solving proportions last week, this week I am working out and solving two-variable inequalities. These are equations that must be solved to show that either they do equal each other or they do not. Most of the time a graph of some kind is necessary to show what the problem is stating. The graphs also show other answers that may fit into the equations to make them correct. In problem 68 on page 539 of Elementary and Intermediate Algebra, we are asked to write the inequality for the provided line graph showing all the possibilities for the number of refrigerators and the number of TV’s that will fit into an 18-wheeler. The graph is provided below (Dugopolski, 2012). Going by the graph the refrigerators are the “x” axis and the TV’s are the “y” axis. With the given info of there being 110 refrigerators and there being 330 TV’s, I have my two points. My points are (110,0) and (0,330). With these two points I can work out the slope of the line.
