  3. Good question, Nick.

    I'm asking you to use point-slope form, yet I don't give you the slope. Pretty nasty, huh? All I give you is two points. Hmmm, can you derive the slope from two points? SUUURREEEEE... there's a formula for that, right?

    Now you have the slope and TWO points... an abundance of information, since you only need one point for point-slope form.

    Which point should you pick???

    Whichever one you want!! (Easy enough?)

    lmk if this helped

  5. during class did you say that you can use either set of points(when doing the point-slope eqaution) as x-sub 1 and y-sub1?
