Question 55480
If you were told that a line goes through the following two points:
(2,2) and
(1,3)

And were given the following instructions:

Graph the line; calculate the slope, x-intercept, and y-intercept, and label the intercepts on the graph.

Could you answer the question? 

You've probably done quite a few problems like that up to this point. 

Your problem is nearly the same as my example...just with scary numbers. You've got to do the same with these points now:

(6.7, 100)
(10.2,80)

Hopefully...that gives you the info you need to figure the rest out yourself...
