Linear Equation Practice Exam

A linear equation is a mathematical expression representing a straight line which has been plotted on a graph. The equation has the form $\mathrm{}$ where $$ and $$ are constants, and $$ is the variable. In it, the highest degree of the variable is 1, as it involves no powers or exponents greater than 1. Linear equations are the essential in algebra and to model relationships in physics, economics, and engineering.
