Inequalities are a special resource to the mathematician richer and more complex than those garden variety creatures we call equations How to Graph a Linear Inequality Graph the equals line then shade in the correct area Follow these steps Rearrange the equation so y is on the left and everything else on the right
Graphs of linear equations are especially effective for representing relationships between things that change at a constant rate and they often do a better job than words or mathematical equations alone In this section we learn about graphing linear inequalities in two variables These are of the form ax by c a b and c are real numbers a and b are not both zero and can be

Solving Equations and Inequalities with the Graphing Calculator We now know that the solution of f x g x is the set of all x for which the graphs of f and g intersect Therefore the graphing calculator becomes an indispensable tool Why explain the use of graphs and create graphs using linear equations Much as the road sign at the right can help you quickly understand a falling rocks hazard ahead graphs are a useful way of conveying information visually
Solutions to one variable linear inequalities can be formatted in any of four ways Using the inequality x 3 for our examples these formats are Inequality notation x 3 Set notation x x 3 Interval notation 3 Graphing We can often solve inequalities by adding or subtracting a number from both sides just as in Introduction to Algebra like this Example x 3 7 If we subtract 3 from both sides we get
