Linear Equation

A linear equation is defined as an algebraic equation in which every expression is either a stable (constant) or the product of a stable and a single variable. Linear equations can have one or more than one variables. It’s happening with great reliability in applied mathematics. A linear function is one whose diagram (graph) is a straight line.


Format of Linear equations:

Below are some forms of Linear Equations.

Linear equations:

A general type of a linear equation in the two variables x and y is

y =mx+b

Here ‘m’ and ‘b’ assign constants. Here the term linear is derived from a graphical line of diagram. That is straight line is occurring at a graph.

General form:


Ax+By+C=0

Where A and B are not both equal to zero.

Standard form:

Ax+By=C

Where A, B, and C are integers.

Slope–intercept form:

y=mx+b

Where m is the slope of the line and b is the y-intercept.
