?

OpenStudy (anonymous):

one sec

OpenStudy (anonymous):

Use the slope formula to calculate the slope of the line containing the points: (-2 3/4, 5) (1 3/4, 3)

OpenStudy (anonymous):

make it (-2.75,5) and (1.75,3) so it's easier to see 3/4=0.75

OpenStudy (anonymous):

okay but how do i find the slope wait would i use y2-y1/x2-x1?

OpenStudy (igreen):

\(m =\dfrac{y_2-y_1}{x_2-x_1}\) \(m =\dfrac{3-5}{1 \frac{3}{4}+2 \frac{3}{4}}\)

OpenStudy (anonymous):

@iGreen will take care of you

OpenStudy (anonymous):

thanks everyone i know what to do know just need a little help thanks

OpenStudy (igreen):

No problem, just tell me what answer you come up with, and I can confirm it.

OpenStudy (anonymous):

okay cool give me a second and i will for sure. Thank you so much

OpenStudy (anonymous):

i got -2.25 sooooo -2 1/4

OpenStudy (yamyam70):

Im lovin this , we are on the same lesson (Just leavin comment here for notification)

OpenStudy (igreen):

No, I don't think -2 1/4 is right..

OpenStudy (anonymous):

hmmmmm let me look at my work

OpenStudy (anonymous):

i just redid it and i got the same answer so i must be doing something wrong

OpenStudy (igreen):

\(m =\dfrac{y_2-y_1}{x_2-x_1}\) \(m =\dfrac{3-5}{1 \frac{3}{4}+2 \frac{3}{4}}\) \(m = \dfrac{-2}{4 \frac{1}{2}} \rightarrow m = \dfrac{-2}{4.5}\) Is that what you got?

OpenStudy (anonymous):

yea and i just figured out what i did wrong i divided wrong i accidentally flipped it lol dyslexic mistake haha

OpenStudy (anonymous):

so i got a repeating .4

OpenStudy (igreen):

Lol, can you divide -2 / 4.5?

OpenStudy (anonymous):

-.4 repeating

OpenStudy (igreen):

Yeah, it's \(-0.\overline{44}\) or \(-\dfrac{4}{9}\).

OpenStudy (anonymous):

so 4/9

OpenStudy (anonymous):

@iGreen

OpenStudy (igreen):

No, it's a negative.

OpenStudy (anonymous):

yea lol i knew that i keep forgetting to type the negative lol. thanks for your help

OpenStudy (igreen):

No problem.
