How to plot Linear Inequality Graph

When linear equations are defined with some restriction which causes its answer to be in a fixed range then the situation is known as linear inequalities. This inequality is implemented in the equation with relations like greater than(>) or less than(<) and less than equal to(<=) or greater than equal to(>=) rather than equals to. Function of a linear inequality includes real number expression which is restricted by any constant integer through inequality relation:

H (x) < a or H (x) > a or H (x) ≤ a or H (x) ≥ a

The derivatives of the function are of variable x and range is decided according to constant 'a'.
The general representation form of linear inequality is as :
H(x)= c0+ c1x1+ c2x2+............+cnxn< 0 or H(x)= c0+ c1x1+ c2x2+............+cnxn ≤ 0
To implement the inequality graph for any linear inequality equation, firstly the calculation of the limits or range is required in which graph is to be plotted. After that the common required terms like intercepts of the Cartesian axes and slope of the line is calculated. When two inequality equations are joined together then the resultant equation is called compound inequality. The inequality graph of a compound inequality equation results in geographical area when it is being plotted on a 2D graph.
Generally compound inequities are joined with conduction(AND) and disjunction(OR) relations. For example:
x>2 AND y<2 in this compound relation there are two lines for x and y which includes the condition that value of x is can't be less than 2 and y is not greater than 2.

For having the solution of complex graphing related queries, students can use the online math tool which is available on various online math tutoring website, Graphing calculator. This tool uses the predefined computational steps which are installed in its program to solve particular type of query by Graphing functions.
