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

Is that second point (7, π^2) ??

if so then
(π^2 - n)/(7-6) = 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?
