<p>Does anyone have a list of commands one would need to put into the calculator so that they could derive the equation of a line with only 2 points?</p>
<p>I don’t know that offhand, but just use slope formula, then plug in one set of the points to find the equation. (Or, I think, you can use two-point form.)</p>
<p>Might I ask what calculator you are using?</p>
<p>If you are using a TI Graphing Calculator, you might want to look on ticalc.org. They have a massive selection programs for the calculator, and I am 100% confident that they will have what you are looking for!</p>
