**FUNCTIONS** (again)

Here's one example  :     a function representing an automobile's speed in mph - x -  and its speed in ft per second - y

So.....some ordered pairs are :

x         y

30     44

60     88

90     132

120   176

This is a linear function    ......the slope is   [ 88 - 44] / [ 60 - 30]  = 44/30  = 22/15

And the equation of this function  is

y - 44  = (22 / 15) (x - 30)

y = (22 / 15)x

Here's the graph :  https://www.desmos.com/calculator/rjxubcceok

We know this is a function because it passes the vertical line test.....

Hey G maybe you should solve this one on your own reason being the scenario has to come from you imagnation, you can make the system simple if you want. But just because someone tells you how to answer somethng doesn't mean you get the learning experience out of it.

Just remember to keep it simple and you'll be good.
