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.
situations in which you need to find missing information.For instance,Exercise 68 on page 174 shows how to use a linear equation to determine the height of a flagpole by measuring its shadow. Sergio Piumatti Equations and Solutions of Equations An equation in x is a statement that two algebraic expressions are equal. For example, and are equations. To solve an equation in x means to find all values of x for which the equation is true. Such values are solutions. For instance, is a solution of the equation because is a true statement. The solutions of an equation depend on the kinds of numbers being consid-ered. For instance, in the set of rational numbers, has no solution
