CPM Homework Help : AC Problem 7-27

Artemis thinks that all lines eventually cross the $x$ -axis. Do you agree? If not, provide a counterexample (that is, find a rule and a graph of a line that does not have an $x$ -intercept).

Hint 1:

Will the line below ever cross the $x$ -axis?

Hint 2:

To write the rule, select several points on the line. What do the points have in common?
