Graphing Linear Equations Calculator

In mathematics, a graphing linear equation represents the graph of the linear equation. We know that the linear equation is defined as an algebraic equation in which each term should have an exponents value of 1. The graph of the linear equation will always result in a straight line. One such example of a linear equation is y = mx + b.
