Question

i needs help with my math

Answer 1

okay let me type them out just wait a min.

Answer 2

I need help finding the slope for these pairs..

(317,1960) and (390,2010)

(-0.05,1960)and (0.70, 2010)

(5,1960) and (9,2010)

(3,1960) and (7,2010)

Answer 3

Example: find the slope if given the points (1,2) and (3,4).

Slope is (4-2) over (3-1). This reduces to 2/2 = 1.

Do the same thing with the given pairs. Show your work. Look up the slope formula and type it in here as a verification that you have it in front of you.

Answer 4

I AM SO CONFUSED

Answer 5

Haha, take a look at this: https://www.mathsisfun.com/algebra/line-equation-2points.html
If it still doesn't help, come back and i'm sure people will help you :P

Answer 6

Have you looked up the formula for the slope of a straight line?

Google "slope of straight line."

Pick any two points from those listed, and type them out here, please.

Answer 7

Thank you @Bobo-i-bo

Answer 8

how do you reduce 50/73. Or you cant reduce that equation?

Answer 9

Are we working on the same problem that you originally posted?

Answer 10

I asked you to type in the for mula for the slope of a straight line. You don't have tod o that, but I would like to know for certain that you know this formula and know how to use it.

Which set of points are you referring to in your 50/73?

Answer 11

yes that was the answer to the first one.

Answer 12

the slope for (317,1960) and (390,2010)

Answer 13

OK. What I'd do there would be to subtract 1960 from 2010. Result? 50.
Then I'd subtract 317 from 390. Result: 73.
Then the slope of the line connecting those two points is, as y ou say, m=50.73. You should label your answer with " m = "

Answer 14

1960 and 2010 are y values, whereas 317 and 390 are x-values. Being careful to keep them in order, you subtract one from the other: (2010-1960) over (390-317) = 50/73.

Answer 15

any questions? If not, please find the slopes in the other three cases.

Answer 16

The slope of a line is the change in y over the change in x, hence that's where the slope formula comes in. Change in y is (y2 - y1) and change in x is (x2 - x1), so the slope is (y2-y1)/(x2-x1). This can be also referred to as rise (the y) over run (x).

Answer 17

You can't reduce 50/73 since the highest common factor between 50 and 73 is 1. I know this because I know that 73 is a prime number. But yes, that's the answer to the first q. ^_^

Answer 18

ya cool im working on the other ones but the second ones answer is 2/0.03

Answer 19

@Bobo-i-bo @mathmale

Answer 20

I'm happy to respond to requests for checks of your work only if you show the work you did.

Answer 21

ya and the thirs one is 25/1

Answer 22

Glad you feel you can do these problems. Again, happy to check over work you've done, but not happy to check answers alone.

Answer 23

im not gonna write the problems down that will take all day and i meant for the third one to be 25/2 and the forth one is also 25/2.

Answer 24

Glad you're making progress. No further comment here.

Answer 25

@mathmale has a good point :P Hmmm all of them are correct but the second answer is put in a very... "unnormal" format

Answer 26

Thank you, Bobo.

Answer 27

what so you mean ?

Answer 28

un normal format?

Answer 29

Check over your work. Perhaps set aside your origianl work and do the problem again. Make certain you've followed the same pattern as you did in finding the slopes in the other cases.

Answer 30

ok

Answer 31

I dont understand I did the problem again and I got 50/.75. Than you simplify that equation by 25. Than you would get 2/.03..... How did I get that wrong?

Answer 32

Sorry, but I can't resist telling you that sharing your actual work with me, all of it, might have saved you time.

The second set of points is (-0.05,1960)and (0.70, 2010)

We could say, "the change in y is 2010-1960), and the change in x is 0.70-[-0.05])."

Yes: the change in y is 50. The change in x is (0.70+0.05), or 0.75. Very good.

So, now you have the changes in both y and x. The slope is (change in y) / (change in x).

"I dont understand I did the problem again and I got 50/.75" You were right this far.
What the other fellow meant by "strange format" was that you left your answer in an awkward format: You have a fraction (0.75) in the denominator.

Grab your calculator and divide 50 by 0.75, please.

Answer 33

thats not right the numbers are (5, 1960) and (9, 2010)

Answer 34

Show your work for this problem, following my example.

The slope is ... ?

Answer 35

ok

Answer 36

One way to share y our work is thru drawing it, in the Draw utility, below:
