Most linear equations are functions (that is, for every value of x, there is only one corresponding value of y). When you assign a value to the independent variable, x, you can compute the value of the dependent variable, y. You can then plot the points named by each (x,y) pair on a coordinate grid.
Solving Two-Step Linear Equations with Rational Numbers. When a linear equation has two variables, as it usually does, it has an infinite number of solutions. Each solution is a pair of numbers (x, y) that make the equation true. Solving a linear equation usually means finding the value of y for a given value of x.
