# What is the pattern in words if you get paid 15 dollars in 1 hour, 22 dollars in 2 hours, 29 dollars in 3 hours?

You can say:
You get $15 for the first hour and$7 for every next.

Or you can say:
You get $8 to get started plus$7 for every hour

You may want to translate that last stement into a lineair equation:

$y = 8 + 7. x = 7 x + 8$

Where $y$ = payment ($), and $x$= hours worked. $7$is called the slope; It tells you how $y$changes for every change in $x$and $8$is the so-called $y$-intercept: where the graph crosses the $y$-axis (the $y$-value for $x = 0$) (of course, in real life you wouldn't get paid that$8 if you made 0 hours! but this is maths)

With the equation you can easily work out your payment for any number of hours worked.
