it deals with the symbols "greater than" and "less than". it also deals with the things that are not equal.
A bivariate linear inequality.
If the equal sign in a linear equation in two variables is replaced with an inequality symbol, the result is a linear inequality in two variables. 3x-2y>7 x<-5
x - 2 is an expression, not an inequality.
Basically. If the inequality's sign is < or ≤, then you shade the part under the line. If the inequality's sign is > or ≥, then you shade the part over the line.

A linear inequality is all of one side of a plane. A quadratic inequality is either the inside of a parabola or the outside.
With the equal sign (=).
They are not. An inequality cannot, by definition, be the same as an equation.
1 + 1 = 3
graph the inequality 5x+2y<4
The inequality sign must be flipped.
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
