Students learn to estimate the solution set, in real numbers, of a linear inequality using graphical methods on a number line and on a Cartesian (x-y) graph. They also learn how to solve inequalities using tables.

Students learn to locate the real number solution of a linear equation using tables. They also learn to locate the real number solution of a linear equation using graphical method on a Cartesian (x-y) graph.

Find the intercepts of a line given a table of values. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Dozens of statistical terms are defined and illustrated in this glossary.
