Inequality is defined as two real numbers or two algebraic expressions which are related with functioning a sign as ‘<’ (less than), ‘>’ (greater than), ‘$\leq$’ (less than or equal) and '$\geq$' (greater than or equal). Inequalities are classified as following types:

1) Numerical Inequalities: Inequalities, which involves numerical only without any variables are named numerical inequalities. The example of numerical inequalities is following as,
Eg: 2 < 6; 5 >1

2) Literal Inequalities: Inequalities, which involve one or more variables, are named literal inequalities.
Eg: a < 5; b > 2; x $\geq$ 4; y $\leq$ 6

3) Double Inequalities: An inequality which have two signs (< or > or ≤ or ≥) is described double inequality.
Eg: 2 < b < 8; 2 $\geq$ y $\geq$ 5

4) Strict Inequalities: If an inequality contains a sign < or >, then it is referred strict inequalities
Eg: Ax + B< 0; Ax2 + Bx + C > 0

5) Slack Inequalities: If an inequality involves a sign ≤ or ≥, then it is referred as slack inequalities.
Eg: Ax + By≤ C; Ax + By $\geq$ C

6) Linear Inequalities: An inequality may involve one variable by linear is labeled as linear inequality with one variable; If it involves two variables, then it is labeled linear inequality with two variables.
Eg: Ax + By < C; Ax + B > C

Graphing Inequalities Calculator is the calculator used to get solutions for inequality problems and obtain the right answers. Inequality Graphing Calculator is a tool for solving and graphing the inequalities.

Below is given a default inequality with different values of x and y, click "Calculate". It will solve for x and y to get the coordinates and then plot a graph.
 

Steps for Graphing Inequalities

Back to Top
Step 1 :  

Observe the given inequality and isolate the variable(x or y).



Step 2 :  

Choose different values for "x or y" other than zero and solve for x or y to get different coordinates.



Step 3 :  

Mark all the coordinates in the graph and join it.

  1. Graph y - 2x > 5


    Step 1 :  

    Given inequality = y - 2x > 5


    Isolating the variable "y" $\Rightarrow$ y > 2x + 5



    Step 2 :  

    At x = 1


    $\Rightarrow$ y > 2(1) + 5


    $\Rightarrow$ y > 7


    At x = 2


    $\Rightarrow$ y > 2(2) + 5


    $\Rightarrow$ y > 9


    At x = -1


    $\Rightarrow$ y > 2(-1) + 5


    $\Rightarrow$ y > 3


    At x = -2


    $\Rightarrow$ y > 2(-2) + 5


    $\Rightarrow$ y > 1



    Step 3 :  

    So, the graph for the given inequality as per the coordinates is given by

  2. Graph y < x2


    Step 1 :  

    Given inequality = y < x2



    Step 2 :  

    At x = -2


    $\Rightarrow$ y < (-2)2


    $\Rightarrow$ y < 4


    At x = -1


    $\Rightarrow$ y < (-1)2


    $\Rightarrow$ y < 1


    At x = 1


    $\Rightarrow$ y < (1)2


    $\Rightarrow$ y < 1


    At x = 2


    $\Rightarrow$ y < (2)2


    $\Rightarrow$ y < 4



    Step 3 :  

    So, the graph for the given inequality as per the coordinates is given by
