System of linear equations - Wikipedia, the free encyclopedia For three variables, each linear equation determines a plane in three-dimensional space, and the solution set is the intersection of these planes. Thus the solution set may be a plane, a line, a single point, or the empty set. For example, as three parall
Linear Equation -- from Wolfram MathWorld A linear equation is an algebraic equation of the form y=mx+b involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x a
Graphing Equations and Inequalities - Graphing linear equations - First Glance Home | Teacher | Parents | Glossary | About Us To graph a linear equation, we can use the slope and y-intercept. Locate the y-intercept on the graph and plot the point. From this point, use the slope to find a second point and plot it.
