What is the slope of the line passing through the points (–3, 4) and (2, –1)?

OpenStudy (anonymous):

A.3/5 B. -5/3 C. 1 D. –1

Nnesha (nnesha):

do you know the slope formula to find slope ??

OpenStudy (anonymous):

Yeah but I forgot it because I haven't done this in a while..

Nnesha (nnesha):

\[\huge\rm m = \frac{ y_2 - y_1 }{ x_2 - x_1 }\] formula to find slope use order pair where \[\large\rm (x_1 , y_1 )(x_2 , y_2)\]

OpenStudy (anonymous):

I'm confused :/

Nnesha (nnesha):

confused about what ??

OpenStudy (anonymous):

Like the formula... I don't know how I would solve the problem with it. Sorry my mind is blank right now lol..

Nnesha (nnesha):

first number in order pair is x and 2nd one is y

OpenStudy (anonymous):

So you subtract the y's and the x's then divide? @Nnesha

Nnesha (nnesha):

yes y's should be at the top (numerator )

OpenStudy (anonymous):

Okay does that mean it would be a fraction?

Nnesha (nnesha):

yes right like in formula y_2 - y_1 divide by x_2 - x_1

OpenStudy (anonymous):

Oh okay I think I know now.. Thank you :P

Nnesha (nnesha):

are you sure ??

Nnesha (nnesha):

so what's the answer ?

OpenStudy (anonymous):

Yes im gonna do it in a second

Nnesha (nnesha):

okay let me know what u get o^_^o :-)

OpenStudy (anonymous):

I got 3/5 :P

OpenStudy (anonymous):

@Nnesha

Nnesha (nnesha):

how ??

OpenStudy (anonymous):

I did 4-(-1) which I got 3 and -3-2which I got 5 so i got 3/5 :/ Am I wrong.. I feel like I did something wrong D:

Nnesha (nnesha):

okay you can sole that way so 4-(-1) = ???

OpenStudy (anonymous):

3

OpenStudy (anonymous):

wait nvm its 5

OpenStudy (anonymous):

wow Im tired or something lol

Nnesha (nnesha):

how |dw:1428980161733:dw|
