y=mx+c do you remember this equation?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

c is the y-intercept and m is the slope

OpenStudy (anonymous):

so what's the value of c?

OpenStudy (anonymous):

|dw:1418055562163:dw|

OpenStudy (anonymous):

To find the slope, you just need to use the slope formula with any two points

OpenStudy (anonymous):

does it have anything to do with rise/run

OpenStudy (anonymous):

-3/

OpenStudy (anonymous):

no need to use rise/run

OpenStudy (anonymous):

oh ok

OpenStudy (anonymous):

no no no, rise is not -3 btw

OpenStudy (anonymous):

so i could use 3 and -3

OpenStudy (anonymous):

as my 2 points on the line

OpenStudy (anonymous):

yes you can

OpenStudy (anonymous):

\[\frac{ y1-y2 }{ x1-x2 }=m\]

OpenStudy (anonymous):

then you can get the answer

OpenStudy (anonymous):

ok
