\[\frac{ y2-y1 }{ x2-x1 }\]
canyou put the points in that form where -4=x1
y1=8
x2=-3
y2=-6
OpenStudy (stephaun):
ok what next im a little confused
OpenStudy (stephaun):
Hello
OpenStudy (anonymous):
\[\frac{ -6-8 }{ -3+4 }\]
OpenStudy (anonymous):
can you simplify that

-14 over 1
OpenStudy (stephaun):
So just -14
OpenStudy (anonymous):
now can you simplify \[-\frac{ 14 }{ 1 }\]
OpenStudy (anonymous):
yes
OpenStudy (stephaun):
ohh ok thanks

do you understand how we did that?
OpenStudy (stephaun):
easier than expected
OpenStudy (stephaun):
yes
OpenStudy (anonymous):
yes when you're given 2 points and it asks for slope put it in
\[\frac{ y2-y1 }{ x2-x1 }\]form this is slope-intercept
OpenStudy (stephaun):
? didn't you already do that

yes i'm just telling you thats slope intercept form the points are always placed in
(x1,y1)(x2,y2)
OpenStudy (stephaun):
ohh ok i learned that i was just over thinking the problem
OpenStudy (stephaun):
Thank you for your help :3
