Answer:
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. Here is a shorter definition, A linear equation is an equation that describes a straight line on a graph. You can remember this by the "line" part of the name linear equation. Standard Form. Linear equations have a standard form that looks like this: Ax + By = C. For example...
