    How to draw f inverse of graph f(x) by the linear equation?
    Like in f(x) = 2x+1?
    Please guide me step by step on how to.

    Say y=2x+1, swap x's and y's around, solve for y.

    This is a reflection of f(x) in the line y=x

    Oh okay I got this but like in this site, it says to find slope for any linear eq. How do we do that? I am still confused. Could you illustrate more.

    Where does it say that...?

    Anyway, how do you plot a straight line? Pick two points you know are on the line and just draw a line through them. If you don't know the inverse, just reflect your f in the line y=x
