@iGreen.

OpenStudy (confluxepic):

Do you know the slope formula.

OpenStudy (confluxepic):

@Paula16

OpenStudy (anonymous):

Honestly i dont i apoligize

OpenStudy (confluxepic):

\[Slope=\frac{ rise }{ run }\]

OpenStudy (confluxepic):

How much does it rise.

OpenStudy (anonymous):

Up to 5?

OpenStudy (confluxepic):

The first thing we must find is if the line is positive or negative.

OpenStudy (confluxepic):

|dw:1419007595172:dw|

OpenStudy (anonymous):

Ok im thinking its Positive up?

OpenStudy (anonymous):

And down negitive?

OpenStudy (confluxepic):

Yes. It is positive.

OpenStudy (anonymous):

Ok

OpenStudy (confluxepic):

http://prntscr.com/5imgqk So can't we eliminate the negative slopes.

OpenStudy (anonymous):

Right

OpenStudy (anonymous):

Eaither C or D

OpenStudy (confluxepic):

\(\Huge\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }\)

OpenStudy (confluxepic):

We have to pick two points.

OpenStudy (anonymous):

I was thinking it would be D?

OpenStudy (confluxepic):

Yes. D is correct.

OpenStudy (confluxepic):

http://prntscr.com/5imhhh

OpenStudy (confluxepic):

Lets pick these points.

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

Positive rises from left to right..

OpenStudy (confluxepic):

\(\Huge\text{Slope } = \frac{ -2 - 1 } { 0 -1 }\)

OpenStudy (anonymous):

You could say the negative one looks like it's positive because it goes up from right to left ..but positive rises from LEFT to RIGHT, not the other way around.

OpenStudy (anonymous):

Oh ok

OpenStudy (confluxepic):

What do we get if we subtract -2 with 1.

OpenStudy (confluxepic):

-2-1=?

OpenStudy (anonymous):

-1

OpenStudy (confluxepic):

I meant -3.

OpenStudy (anonymous):

Wait yeah because diffrent signs

OpenStudy (confluxepic):

\(\Huge\text{Slope } = \frac{ -3 } { 0 -1 }\)

OpenStudy (confluxepic):

Like that.

OpenStudy (confluxepic):

And then we do 0-1.

OpenStudy (anonymous):

Thank you both of you for helping me i appricate it very much! But i got the answer now! Again thank you

OpenStudy (confluxepic):

\(\Huge\text{Slope } = \frac{ -3 } { -1 }\)

OpenStudy (anonymous):

Nice work. @confluxepic

OpenStudy (confluxepic):

Thanks.

OpenStudy (confluxepic):

Okay. @Paula16 The negatives can cancel out on both sides to make the overall formula positive.

OpenStudy (anonymous):

Right

OpenStudy (confluxepic):

\(\Huge\text{Slope } = \frac{ 3 } { 1 }\)

OpenStudy (anonymous):

So then its C or D and i said d

OpenStudy (confluxepic):

Yes.

OpenStudy (confluxepic):

Do you know anything over 1 is that number.

OpenStudy (confluxepic):

\(\Huge\frac{ x } { 1 }=x\)

OpenStudy (confluxepic):

\(\Huge\frac{ 3 } { 1 }=?\)

OpenStudy (anonymous):

Sorry Back , and 3?

OpenStudy (confluxepic):

Yes.

OpenStudy (confluxepic):

\(\Huge\frac{ 3 } { 1 }=3\)

OpenStudy (confluxepic):

So the final slope would be 3.

OpenStudy (anonymous):

Thank you again! I appricated it!

OpenStudy (confluxepic):

You're welcome.

OpenStudy (anonymous):

See theres this test it has 26 questions im on 19 so i needed a little help

OpenStudy (confluxepic):

Ok.

OpenStudy (confluxepic):

Just tag me if you need help. Or tag @iGreen. He is also good at math.

OpenStudy (anonymous):

Ok! :)
