FNGR 1 | Lesson 3 | Solution 1

For each value of $$x$$ increasing by 1 the value of $$y$$ increases by 3 or there is a constant rate of change of 3.
When $$x = 3$$, $$y = 11$$. When $$x = 5$$, $$y = 17$$.
When $$y = 29$$, $$x = 9$$
This is linear because it grows by adding 3 for each consecutive value of $$x$$.
