<h1>How to Graph Linear Equations</h1><strong> Author: <a href='http://www.articleseen.com/profile_mahan.aspx'>mahan</a></strong><br /><p><p>Hey! Are you anxious about your math skills or face difficulty while solving maths problems, then online free math help is provided for you by various free online math tutoring websites. Because of online free math help, you can have all the solutions for your math queries and you do not need to go anywhere else. Online free math help is useful for every student to excel his mathematical skills. Free online math help uses visual lessons to explain mathematical principles more clearly to students.</p> <p>Let us see how online math tutor describes graphing linear equations , Any linear equation is an algebraic equation which consists of all its derivatives of first order. A linear equation formed by the combination of integer constant or product of constant with variable and a single variable. For graphing linear equations, first step is to recognize that the equation with two variables is a linear equation. The standard form of two variable linear equation is </p> <p>Ax + By = C here A, B and C are constants and x, y are variables . Let us take an example ; y= 9x -2 now subtract '9x' from both sides y - 9x = -2 now this is in the form of standard linear equation.</p> <p>Now for graphing this linear equation, we need co-ordinates of x and y relatively. This can be done by putting 3 random values of x in the above equation and than calculate y 's value corresponding to each x value. For example: lets take values of x as ( 1, 2, 3) and with the help of equation, calculate y's value: when x =1, than ( y – 9(1) =-2 ) gives y = 7 when x =2, than ( y – 9(2) =-2 ) gives y = 16 when x =3, than ( y – 9(3) =-2 ) gives y = 25 Now we have three co- ordinate pair (1,7), (2,16), (3,25) , which is enough to plot a graph for linear equation. </p> <p>For learning more about graphing of linear equation and many other topics of mathematics, online free help is available on various online tutoring websites. Like For solving all the complex problems related to term algebra, students can refer to online algebra problem solver.
