x1,y1 =2,25 x2,y2= 4,50

hartnn (hartnn):

any luck finding slope for B?

OpenStudy (anonymous):

Not yet, still working on A

hartnn (hartnn):

choose all the options which has greater slope than what you found for B

OpenStudy (anonymous):

Alright. Hold on.

hartnn (hartnn):

Actually just saw that the table is for B and not A

OpenStudy (anonymous):

How do i get the slope for B? I'm not used to doing slope for things that aren't on a graph.

hartnn (hartnn):

you just need 2 points to get the slope

hartnn (hartnn):

\(\Large m =\dfrac{y_1-y_2}{x_1-x_2} \)

hartnn (hartnn):

from the table you can choose ANY 2 points say if you choose x1,y1 =2,25 x2,y2= 4,50

hartnn (hartnn):

then your slope equation will look like \(\Large m =\dfrac{y_1-y_2}{x_1-x_2} = \dfrac{25-50}{2-4} = \)

OpenStudy (anonymous):

Ohhh, so pretty much i turn it into that, okay. Hold on.

OpenStudy (anonymous):

\[\frac{ 25 }{ 4 }\] Right?

hartnn (hartnn):

4 or 2 ?

hartnn (hartnn):

denominator should be 2 m =25/2 =12.5

OpenStudy (anonymous):

2 sorry i completely forgot about the bottom part

hartnn (hartnn):

all slopes greater than 12.5 from the choices are your answers :)

OpenStudy (anonymous):

Alright, thankss.

hartnn (hartnn):

welcomess ^_^
