Good question... a TRUE ALGEBRATICIAN would check it out. How can you check it out you ask? I-m glad you asked ;).
Use point-slope form TWICE - call it a cross-check, once with each of the two sets of points. You should get the same equation, right. Think about what you are doing.
I'm giving you two points on a given line. You are able to figure out the slope. Picture it... that line is in one definite place on the coordinate plane. There is only one slope-intercept form equation that would be a fit for it, right?
So you can use ANY point on that line to start working with point-slope form. I guess we could rename it ANY-POINT-slope form, do you agree?
Actually, yes you have. If you compare the text book sections to what we have actually covered, you and your classmates have done quite a bit.
I plan to give a surprise quiz on Monday... similar to one of the problems from Problem Set 5B #1-4. Of course, if you're reading this, there should be no surprise! If you have done the homework, you should have no problem.
Feel free to spread the word to your non-blogging friends!
This Blog exists for the collective benefit of all algebra students. All questions are welcome. The more specific your question (including your own attempts to answer it) the better.
EVEN MORE WELCOME ARE ANSWERS FROM FELLOW STUDENTS. BLOG ON!

ReplyDeleteduring 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?

lmk if this helped!

aww man.i was already doing walking in a mid-terms wonderland..PLEASE DON'T DO IT EVERYONE ELSE!!!!
ReplyDeletewait....do we really have a quiz on the 14th cause i don't think we did 5,6 or 5,5 did we?oh no..............what should we study...
