Question

How to find the equation of the tangent line given a graph and a point?

Answer 1

got equation?

Answer 2

No, just the graph of F'

Answer 3

Let f(x)be the equation of the graph curve and (c,d) be the coordinates of the point on the curve.
y = m x + b is the equation of the general slope/intercept line.

Solve the following for b.
d = f ' (c) c + b
The tangent line equation is:
y = f ' (c) x + b
