    Find the tangent line of 6x/x+5 at the point (3, 2.25)

    I got the derivative, but how do you find the slope of the tangent line from those points?

    You just plug x=3 into the derivative to get the slope of the tangent line. I assume you mean y=6x/(x+5).

    What did you get for the derivative?
