# Inverse graph? watch

1. 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 , swap x's and y's around, solve for y.

This is a reflection of in the line

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 in the line
