| The equation p=0.69d is an example of an equation in two variables . A solution of an equation in two variables is an ordered pair that results in a true statement when substituted into the equation.

| Since the solutions of an equation in two variables are ordered pairs, the equation describes a relation. So, in an equation involving x and y, the set of x values is the domain, and the corresponding set of y values is the range.

| Make a table. The values of a come from the domain. Substitute each value of a into the equation to determine the values of b in the range.

| You can graph the ordered pairs in the solution set for an equation in two variables. The domain contains values represented by the independent variable. The range contains the corresponding value represented by the dependent variable.

| When you solve an equation for a given variable, that variable becomes the dependent variable. That is, its value depends upon the domain values chosen for the other variable.
