Question

What is meant by the linear equations?

Answer 1

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. A simple example of a linear equation with only one variable, x, may be written in the form:ax + b = 0, where a and b are constants and a ≠ 0. The constants may be numbers, parameters, or even non-linearfunctions of parameters, and the distinction between variables and parameters may depend on the problem (for an example, see linear regression).
CONCLUSION

A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: 

It has one or two variables.No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.
