−3
Negative 1 over 3
1 over 3
3
OpenStudy (will.h):
Pick any 2 points lays on that line
OpenStudy (ladylauren):
so 1,3 and 2,6
OpenStudy (will.h):
Okay
Now use the slope formula
Slope = y2 - y1/ x2 - x1
Where y2= 6 And y1= 3 and x2= 2 and x1= 1
Substitute the values in the formula and simplify
Still Need Help?

i don't get it
OpenStudy (ladylauren):
so slope intercept form is
y=mx+b
OpenStudy (will.h):
Slope = y2 - y1/ x2 - x1
Where y2= 6 And y1= 3 and x2= 2 and x1= 1
Substitute the values in the formula and simplify
So now
Slope = 6 - 3/2 - 1
I just substituteD the values
Make sense?
OpenStudy (ladylauren):
no :( i stink at these prob
OpenStudy (will.h):
Okay. Let's forget about the formula
Do you know how to apply rise over run? Through the graph..

kinda its change in x over change in y
