Example 2

Does the ordered pair (5, 19) satisfy the function [math]g(x) = 5x – 6[/math]? Does it satisfy the inequality [math]y > 5x – 6[/math]?

[list=1] [*]Rewrite the function [math]g(x) = 5x – 6[/math] so that it is not in function notation. [*]Substitute the ordered pair into the function and simplify. [*]Substitute the ordered pair into the inequality [math]y > 5x – 6[/math] and simplify. [/list] This applet is provided by Walch Education as supplemental material for their mathematics programs.
