what is the positive value of n if the slope of the line joining (6,n) and (7 pie squared) is 20?

math 
Reiny,
Is that second point (7, π^2) ??
if so then
(π^2  n)/(76) = 20
π^2  n = 20
n = π^2  20 or appr. 10.13
I have a feeling you have a typo.
Why would you ask for the positive value of n if there is only one answer and that answer is negative?
