Find the equations of the tangents to the following graphs for the given values of x.

(a) y = ln x, where x = 1/2

2. Relevant equations

3. The attempt at a solution

I know ln x differentiated is 1/x but I cannot see when the rest fall into the place. The book I'm using doesn't explain it at all well.

Answer: y = 2x - ln 2 - 1

Thank you for looking :)
