This document discusses linear inequalities in two variables. It explains that linear inequalities look like linear equations but use <, >, ≥, or ≤ instead of =. Solutions to inequalities are ordered pairs that make the inequality true. Examples are given of checking solutions to inequalities and graphing various one- and two-variable inequalities on a coordinate plane.
This slide introduces the concept of linear inequalities in two variables.
Linear inequalities resemble line equations, featuring <, >, ≥, or ≤. Solutions are ordered pairs (x, y) making the inequality true.
This slide presents the task of checking if (0, 1) satisfies the inequality 2x + 3y ≥ 5.
Prompts the audience to check if (4, -1) and (-3, 2) are solutions for the inequality 2x + 3y ≥ 5.
This slide demonstrates graphing the inequality y < -2.
Another graphing example showing how to graph the inequality x ≥ 1.
Encourages the audience to graph the inequalities y≥2 and x>1.
Presents an example where the inequality y < 2x - 3 is to be graphed.
This slide prompts the audience to graph the inequality y > -x – 4.
Demonstrates how to graph the inequality 2x – 5y ≥ 10.
Encourages the audience to graph the inequality 4x + 2y ≥ 8.
