Question

Answer 1

I'll spend as much time with you as you need to get this problem solved, but I'd bet you already know most of the answer from our previous work this afternoon.

Answer 2

i think it is that we can graph the lines and see if they intersect, at any point

Answer 3

Certainly, but the main focus of this exercise lies in EXPLAINING how you come to your conclusion about whether or not the lines representing the data will ever intersect. This was precisely the focus of our previous question. what did we do in the previous question?

Answer 4

we focused on different y intercepts and slopes to find out if they would ever intersect

Answer 5

right, and we learned that if 2 straight lines with different y-intercepts have the same slopes, they'll never intersect. So all you really have to do is to determine the slopes of the lines that represent the data in the 2 tables. If the slopes are diff. then the lines may or may not intercept in the 1st quadrant (we don't care about the other 3 quads); if the slopes are the same, and the y-int. different, then .... what?

Answer 6

they will intersect at a certain point

Answer 7

Remember: equal slopes <=> no intersection (unless one line coincides with the other one).

Answer 8

So: please reword your response to my question.

Answer 9

oh they will be parallel to each other

Answer 10

and will not intersect. that's the whole focus of this homework question.

Answer 11

think you can finish this yourself? I'll give you a choice: we finish this problem and then i stop, or we go thru an entire new problem right now (provided you're up to it).

Answer 12

ill finish it

Answer 13

it will take you some time. Please use the slope formula to find the slope of the line representing the data in each of the 2 given tables. Compare the slopes. Determine wehther or not those 2 lines could intersect in Q1. We don't care if they intersect in any of the other quadrants. Determine wehther the lines representing the data in the 2 different tables coincide or do not coincide. OK? I'd estimate this will take you 5-12 minutes. I'm reading the paper and cleaning up while you do that.

Answer 14

they don't give me tables ...

Answer 15

In that case you'll have to imagine the tables. What would you do? We'd assume that the data is all linear (that is, if you were to plot it, all the data points would lie in a straight line). Take any 2 pts. in each table and find the slope of the line segment that connects those 2 pts. Then compare the resultant slopes. Again, if you don't actually have the tables, you can stilld describe what to do.

Note that you need to determine whether or not the 2 lines have the same or different y-intercepts, as well as the same or different slopes, and then respond to the home3work question accordingly.

Answer 16

yes i think i got it it is similar to the one before..

Answer 17

i am kind of in a rush so well have to move on :)

Answer 18

OK. I've been on OpenStudy most of the day and would like to excuse myself for a while. But if you'd post one or two more questions, I'd look at them later (but no promise that it would be tonight).

Answer 19

ok thank you!!

Answer 20

As always, it's really been a pleasure to converse with you. See you soon!
