<h1>Graphing linear inequalities and online math tutor</h1><strong> Author: <a href='http://www.articleseen.com/profile_mahan.aspx'>mahan</a></strong><br /><p><p><p>Friends today we all are going to learn the basic concept behind linear Inequalities and how online math solver helps to graph linear inequalities. Firstly we need to understand what does Inequalities means in Maths ? An inequality tells that two values are not equal. For example 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 of a line in the plane is defined as the change in the y coordinates divided by change in x coordinates, between two distinct point on a line. Math solver needs to understand the general form of slope which is called as slope intercept form.</p> 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. </p> <p>Let's take an example to understand the linear inequalities: How to solve a compound inequality and graph the solutions? Example: -6 < 2x - 4 < 12 -6 < 2x - 4 < 12 add 4 to all 3 parts -2 < 2x <16 divide 2 from all 3 parts -1 < x < 8 </p> <p>To graph the following equation, you put an open circle or we can say mark it by a dot on the point (-1,0) and then you put an open circle on the point (8,0).Then draw a line between the two.</p> <p>We need to be careful while solving inequalities, as they are harder to solve than equations and require more attention. You can multiply an equation by a positive or negative number and get an equivalent equation. But while solving Inequalities remember this: when multiplying it by a negative number, you need to change sign of the inequality.</p> <p>A linear inequality describes an area of the coordinate plane that has a boundary line. In simple way in linear inequalities everything on one side of a line on a graph. </p> <p>In mathematics a linear inequality 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 ≦ or ≤ less than or equal to etc.</p> <p>Linear inequality is also a part of algebra, as various algebra tutors or equation solvers are available to solve the equation. It generates answer on one click by user on solve option and also shows the student how to arrive at the answer.</p> </p><strong>About the Author:</strong><br /><p>TutorVista is the #1 portal for learning <a rel="nofollow" href="http://worksheets.tutorvista.com/math/86949/graphing-linear-inequalities-in-two-variables.html" title="graphing linear inequalities">graphing linear inequalities</a> online.
