Chapter 3, Problem 77(choose chapter or problem)
In Exercises 77 and 78, find an equation of the tangent line to the graph of the function \(f\) through the point \(\left(x_{0}, \ y_{0}\right)\) not on the graph. To find the point of tangency (x, y) on the graph of \(f\), solve the equation
\(f^{\prime}(x)=\frac{y_{0}-y}{x_{0}-x}\).
\(f(x)=\sqrt{x}\)
\(\left(x_{0}, \ y_{0}\right)\) = (- 4, 0)

f
(x_0, y_0)
f’(x) = y_0 - y /x_0 - x
f(x) = sqrt x
