Algebra 2 – 2.6 LINEAR INEQUALITIES IN 2 VARIABLES

Linear Inequality An inequality that can be written in one of the following forms: y > mx + b y < mx + b y ≥ mx + b y ≤ mx + b In other words, it is the same thing as a linear equation, but with a sign of inequality instead of an equals sign BUT that sure makes for a big difference…

Solution A solution is a point, written as (x, y) that you could plug in and have a true statement of inequality y > 2x + 3 Name three solutions.
