( 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.
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.
A linear inequality is described as 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.
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 ≦ or ≤ less than or equal to etc. Now the next stage to solve a problem is to write the inequalities in a slope intercept form or in the form of y = mx b.
secondly: temporarily exchange the inequality symbol for the equal symbol. For example
y
Thirdly : Use different values for x to find points that will be graphed in the form (x,y).
like when x=3, y = 4 and when y = 3 x = 4.
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 an x-y axis. Addition principle for solving problems of Inequalities is - If a > b then a c > b c .

Here is an another description about Linear inequalities Expressions which include Combination of variables and constants as well as operators can be defined as Linear inequalities. Since it is an inequality it must contain either a greater than sign or a less than sign. These signs are represented as ‘<’ and ‘>’.
