If you have a function f(x), then the tangent can be found by deriving f, denoted
d/dx(f(x)) = f'(x). This will give the slope of f(x) at a certain point (a,b).
find f'(a), call this m. Now, use the standard form for a line, y = mx+c, plug in the point (a,b) to solve for c. Finally, the equation for the line tangent to a point (a,b) and f(x) is y= f'(a)x + c

Find the slope of a tangent line to the graph?
Use calculus, to differentiate. e.g. y = x^(2) The differential is dy/dx = 2x So in the graph at the point x = 1 y = 1^(2) = 1 The slope at this point ( 1,1) is dy/dx = 2(1) = 2 So in the graph at the point x = 3 y = 3^(2) = 9 The slope at this point (3,9)is dy/dx = 2(3) = 6
