Implicit Differentiation:
----------used quotient rule

This rate of change as a slope value at (1,1) is:

.

Assumption is that point (1,1) is on the curve given. The equation for line tangent to the curve at (1,1) easily found using the point-slope equation form:

---------in slope-intercept form
