y-hat = 1389 + .96x

Draw a graph of this line, with x running from 3000 to 4000 lbs per square inch.

-----------------------

I don't know how to graph it because the words are confusing me . . . I labed my explanatory (x-axis) as psi from 3000 to 4000 lbs and the response variable (y-axis) as days. How do I graph 1389 (the intercept) on my graph if the y-axis is days?
