Friends if you find difficulty in solving mathematical problems or afraid of maths, then you don't need to worry. You must have heard about Online tutoring service provider TutorVista. It is an educational website which helps you in learning mathematical concepts and removes your mathematical obstacles. It is especially designed to help students who finds difficulties in mathematics and it also helps in scoring high marks in mathematics.

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. Let's take an example to understand the linear inequalities:

Example: -8 < 2x - 4 < 16

add 4 to all 3 parts

-4 < 2x < 20

divide 2 from all 3 parts

-2 < x < 10

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 (10,0).Then draw a line between the two.

Today we all are going to learn about the basic concept behind Inequality. An inequality tells that two values are not equal. For example a ≠ b shows that a is not equal to b. A linear inequality describes an area of the coordinate plane that has a boundary line. In simple way in

**linear inequality graphs**everything is on one side of a line on a graph.
In mathematics a

**linear inequality i**s an inequality which involves a linear function. To**solve Inequalities**we must remember the symbols showing inequalities like the symbol < means less than and the symbol > means greater than and the symbol รข‰¦ or ≤ less than or equal to etc.Slope formula plays an important role in graphing linear inequalities.
