Point-Slope

Standard

I honestly have no clue how many times / classes / students I’ve taught Point-Slope as a rote formula to memorize, plug in values and simplify. ┬áNo discussion, except that its derived from the slope formula.

But after some discussion / great convo on Twitter, I’ve arrived at the solution for now.

To introduce it simply as a vertical translation of a direct variation graph.
