§ 8.1 Graphing and Writing Linear Functions
Martin-Gay, Beginning and Intermediate Algebra, 4ed 3 Identifying Linear Functions By the vertical line test, we know that all linear equations except those whose graphs are vertical lines are functions. Thus, all linear equations except those of the form x = c (vertical lines) are linear functions. Linear Functions

Martin-Gay, Beginning and Intermediate Algebra, 4ed 4 Let x = 4. f (4) = 3 + 3 = 6 S implify the right side. One solution is (4, 6). Graph the linear function f ( x ) = x + 3. 4 3 f (4) = (4) + 3 R eplace x with 4. 4 3 Graphing Linear Functions Example: Continued.
Martin-Gay, Beginning and Intermediate Algebra, 4ed 5 For the second solution, let x = 0. f (0) = 0 + 3 = 3 S implify the right side. So a second solution is (0, 3). Graph the linear function f ( x ) = x + 3. 4 3 f (0) = ( 0 ) + 3 R eplace x with 0. 4 3 Graphing Linear Functions Example continued: Continued.
