You want a vector <a,b,c> which is perpendicular to the two given vectors, that is,
you want the cross-product of the two given vectors.
once you have that , the vector equation would be
r = (5,2,1) + t(a,b,c)
I assume you know how to find the cross-product
let me know what you get

I got (-3, 2, 6) as my cross product.
So the final answer would be r = (5,2,1) + t(-3,2,6).
Thank you so much for your help!
