the slope of?
OpenStudy (anonymous):
of what?

rise over run
how many units does it rise and how many does it run put it in fraction form

pick any two points on the line, let's see if we can get the slope by just getting 2 points from it
OpenStudy (kendricklamar2014):
Is it C?
OpenStudy (jdoe0001):
the points? there's no point "c"
pick any 2 points from the line, let's see if we can get the slope from 2 points in it
OpenStudy (kendricklamar2014):
Is the answer C?
OpenStudy (anonymous):
you are riseing 2 and runing 1 so 2/1 = 2

Did you do what @jdoe0001 asked you to?
OpenStudy (kendricklamar2014):
I dont know what he means?
OpenStudy (anonymous):
You can use any two points on the line, like (1,0) and (0,2). Then use m = y2-y2/x2-x1

(-1,4) (2,-2) those points
OpenStudy (anonymous):
Ok so use rise/run, \[m=\frac{ y _{2}-y_{1} }{ x _{2}-x _{1} }\] where m represents your slope.
OpenStudy (kendricklamar2014):
-1 - 2, 4 - -2

so slope is rise over run.
you rise 2 run 1. So you have 2/1 that is equal to 2.
I think that is b
