Let's tackle LITERAL equations for a while.
identify the difficult areas
build some quick and easy rules we could refer back to at a later time.
Linear Equations:
What does it mean to be a linear equation?
Let's play a little bit:
student.desmos.com: P57N
forms of a line used through play
slope intercept is most common to us
point slope is going to be MORE useful to us
Standard has it's uses -- but not for what we're doing right now
Now, back to the homework question -- how can we best fit a line to the data?
I've 'desmos'd it for you here: https://www.desmos.com/calculator/wkvcudqvza
what for of a line works best for us?
talk of residuals
Outro Question: nim.
