Take a look at the Related Questions below. The general outline for solution is:

find the slope of the tangent to the curve at any x: dy/dx

evaluate y' at the given x. That will provide the slope of the line you want.

Now you have a point and a slope. Use the point-slope form of the equation for a line.
