1. The problem statement, all variables and given/known data The following point (x0,y0), is on the curve sqrtx +sqrty = 1 Show that line equation of the tangent line in the point. (x0,y0) Is x/sqrtx0 + y/sqrty0 = 1 I've found the slope which is -sqrty/sqrtx. So slope of the point is -sqrty0/sqrtx0 2. Relevant equations 3. The attempt at a solution y-y0=-sqrty0/sqrtx0(x-x0) Should I get the solution from the equation above?
