I was just wondering if any one could help me find the solution to this problem:
If L is a tangent to the curve with equation sqrt( x )+sqrt(y)=sqrt(c ), show that the sum of intercepts of L is equal to c
I was just wondering if any one could help me find the solution to this problem:

If $\displaystyle a\ne 0~\&~b\ne 0$ can you show the slope at $\displaystyle (a,b)$ on that curve is $\displaystyle -\frac{\sqrt{b}}{\sqrt{a}}~?$
Then what is the equation of the tangent line there?
