Friends, today we all are going to learn the basic concept behind linear inequality in mathematics and the

(m = y2-y1/x2-x1 ) where x1 is not equal to x2.

In general slope intercept form denotes the formula: y = mx + b.

where m = slope of the line

b = y intercept.

In mathematics, a linear inequality is an inequality which involves a linear function. For solving inequalities we need to learn the symbols of inequalities like the symbol < means less than and the symbol > means greater than and the symbol ≤ less than or equal to etc.

Lets see an example to show a

Add 2 to all 3 parts in an equation

-4 < 2x < 10

Divide 2 from all 3 parts

-2 < x < 5

To graph the following equation, you put an open circle or we can say mark it by a dot on the point

(-2,0) and then you put an open circle on the point (5,0).Then draw a line between the two.

**graphing**concepts used in an**inequality graph**. Before proceeding further let’s talk about inequality. Inequality basically tells that two values or expressions are not equal. For example, to understand it betterment a ≠ b shows that a is not equal to b. Slope formula plays an important role in graphing linear inequalities. So we need to know what slope formula means. Slope of a line describes the steepness, incline, or grade of the straight line. The slope through the points (x1, y1) and (x2, y2) is given as slope formula.(m = y2-y1/x2-x1 ) where x1 is not equal to x2.

In general slope intercept form denotes the formula: y = mx + b.

where m = slope of the line

b = y intercept.

**linear inequality**describes an area of the coordinate plane that has a boundary line. In simple way, in linear inequalities everything is on one side of a line on a graph.In mathematics, a linear inequality is an inequality which involves a linear function. For solving inequalities we need to learn the symbols of inequalities like the symbol < means less than and the symbol > means greater than and the symbol ≤ less than or equal to etc.
