Online Help in graphing equations

Friends TutorVista is the Online service provider. It is basically an educational website which helps you in learning complex and new concepts of the mathematical world. This educational website or service provider is especially designed to help those students who find difficulty in solving maths questions.

Friends today we all are going to learn the basic concept behind Linear Inequalities and How to Solve Inequalities. Firstly we need to understand is What does Inequality means in Maths? An inequality tells that two values are not equal. For example a ≠ b shows that a is not equal to b. A linear inequality is 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 รข‰¦ or ≤ less than or equal to etc.

Graphing equations comes with a large number of complexities which may cause lots of problem to the user or student. Lets see one example of Linear Inequality graph. To solve a linear inequality problem is to write the inequalities in a slope intercept form or in the form of y = mx + b. Now the next stage is to temporarily exchange the inequality symbol for the equal symbol. For example y <= -x + 2 becomes y = -x + 2 after exchanging the symbol. Now use different values for x to find points that will be graphed in the form (x,y).

like when x=3, y = -1 and when y = 3 x = -1

At last we need to draw lines on the graph using these above values. Point slope refers to a method of graphing a linear equation on x-y axis.
