Rate of Change Has Another Name!
Today's class went quite well. I want you to visit this website and investigate slope. You will see some new words and symbols which you may be able to understand without my help. If not, we will clear matters up on Thursday.
For Thursday:
1. Complete Covering the Reading in Lesson 7-2.
2. Finish the questions in Lesson7-1 if you have not done so already.

Hi Mrs. Burke,
I checked out the web site and I thought it was fun moving the line around. If you put it vertically, the box says "undefined."
How did we do on the tests? Can I see mine tomorrow if I stop by?

Dear Mrs. Burke,
I have questions on 7-1, I do not fully understand rate of change. Can I see you at break or in the morning tomorrow? I have sports after school, but can I take my test at lunch tomorrow or will I need more time?
See you at school!

Hi Mrs. Burke,
That website is so cool! It really helped me understand slopes.
Hope we did well on the tests!
See you in the hallway.

Brendan, you can take Part 1 of the test during lunch. Everyone finished both parts in about 5o minutes.
AMS, glad you liked the website. I thought it would be fun and help you all visualize slope better.
Mrs. Burke,
I thought the test today was pretty easy. I am not surprised everyone finished so early.

wiesej, why is the slope undefined when the line is vertical?
edg, did you visit the website?
Mrs. Burke,
I set the slope vertically and it said undefined. I'm not sure why.

I know why the slope is undefined when the line is vertical. Would you like wiesej to comment with the answer since it is wiesej's question or are other people allowed to answer? I know sometimes we answer each other's questions, but I am just not sure.

Please feel free to reply to another student.
Hey Mrs. Burke,
I thought the website was very helpful in understanding slopes. I used it to check my homework.
See you tomorrow.
Hi Mrs. Burke,
I now understand why the vertical slope is undefined! I just hadn't read the lesson 7-3 yet, so I didn't understand it.
See you tomorrow!

Dear Ms. Burke,
I was thinking: How can you tell which is x1 and which is x2? Is x2 simply the one with the higher value, or the second one when given a list? If I were faced with two coordinates, would I be able to seperate which is x1 and which is x2?
Hey person52,
x2 is the second x-coordinate, when given more than one set of coordinates. The same applies to the y-coordinates.
How was Boston Mrs. Burke?
See you Monday!
AMS
I think that person52 is asking how do you know which is the first and the second if you are just given a graph with points.
KES
I am actually wondering this too (if you are given no prior information.)
KES
I'm also wondering that too! In the past we've been given easy problems for this, but I don't actually know what to do if the scenario comes up that person52 desrcibed.
Volunteering at the auction was fun!
