I have an equation of P=(1703x)(x25)
How do I determine the yintercept
I know I can determine the x intercepts by setting x = to zero, so those are easy to find, but I'm not sure how to find the yintercept.
Thank you.

no,
you find the xintercept by letting y equal to zero, and
you find the intercept by letting x equal to zero.
so ....

Yes, sorry, that's what I meant to say.
So I find the x intercepts by saying
170  3x = 0 and solving and
x  25 = 0 and solving.
I found those to be
(25, 0) and (56.67, 0)
But if I set x equal to zero here, the x intercept will be (0,0)
I have the solution as (0, 4250) but I don't see how to get that

P=(1703x)(x25)
so if x = 0 , we have
P = (1700)(025)
= 170(25)
=  4250
so the point is (0, 4250)
well, how about that?

Oh my  so sorry!!!
Yes  thank you!! Please call it the Sunday blues.....
