I'm totally stuck.
Any help would be appreciated.

You can describe any line through the point {1,1} by selecting a unit vector {a,b} and putting:
{x[t],y[t]}={1,1}+ t{a,b}.
Go with
f[x,y]=x^2y
and say how you should set a and b so that the derivative of f[x[t],y[t]] with respect to t is as big as possible when t=0.

Anything that could help walk me through and figure out what I need would be best.
