A linear inequality can be graphed either on a number line for a one-variable linear inequality or on a coordinate xy plane for a two-variable inequality.
. A linear inequality usually looks like a linear equation where the equal sign has been exchanged for a greater than a less than a greater than or equal to or a less than or equal to sign. Y 2x 4. Intro to graphing systems of inequalities.
Then find the y-intercept by setting x equal to 0. For and use a closed dot to indicate the. The x-intercept is 2 0.
Graphing systems of inequalities. First graph the inequality as the equation. Then repeat the process for the.
Two-variable inequalities from their graphs. Graphing Solution Sets of Linear Inequalities. Always start by isolating the variable color redy y on the left side of the inequality.
