Hi all,

This is the following homework problem I am having trouble with:

Consider the surface: 25x^2+25y^2+1z^2=51

P=(1,1,1) on this surface.

So far, I have gotten:

x=1+50t

y=1+50t

z=1+2t

The equation to the plane P must be written as z=, so I wrote:

z-1=50(x-1)+50(y-1)

z=50(x-1)+50(y-1)+1

Whenever I type this into the online homework, it displays "incorrect". Any suggestions?

Thank you in advance!
