This lesson is the first in a series of three on linear inequalities. Students studied one-variable inequalities in grade 8, as well as graphing and solving linear equations, but this is the first time they have graphed, written, or identified solutions for linear inequalities.

Plot three points on the graph so that the value of $$y$$ in each ordered pair is greater than the value of $$x$$.

A student was given the following inequality to graph.
$${2x-3y\leq 9}$$
The graph this student created is incorrect. Explain the error(s) this student made and then graph the inequality correctly.
