I choose C ^^^^^
OpenStudy (anonymous):
Why C?
OpenStudy (anonymous):
16 , 32 = (+ )
OpenStudy (anonymous):
2-4=2 which is +2

incorrect, it's not C
OpenStudy (anonymous):
\[y-y _{1}=m(x-x _{1})\]
OpenStudy (anonymous):
well I had two one I choose .. B or C
OpenStudy (anonymous):
32-16 =16
OpenStudy (anonymous):
-16

so i am now thinking it is B
OpenStudy (anonymous):
\[Slope = \frac{ y _{2}-y _{1} }{ x _{2} - x _{1}}\]
OpenStudy (anonymous):
\[Slope = \frac{ 32-16 }{ 4-2 }= \frac{ 16 }{ 2 }= 8\]
OpenStudy (anonymous):
2-16=14
4-32=-28
6-48=-42
8-64=-56
OpenStudy (anonymous):
oh I see

so if i am correct i think its A ^^^^
OpenStudy (anonymous):
Yes
OpenStudy (anonymous):
You are correct! c(ˊᗜˋ*c)
OpenStudy (anonymous):
yay .. I skipped one of the steps with the slope , I get this problem now thanks ,. :p have a great day
OpenStudy (anonymous):
No problem.

@Mateaus Can you explain me why A but C?
OpenStudy (anonymous):
Well the point slope formula is \[y-y _{1} = m(x-x _{1})\] You are given the points already which are positive. So we have:\[y - (+16) = 8 (x-(+2))\]
OpenStudy (anonymous):
That's how we get A instead of C
OpenStudy (loser66):
Clear. Thanks a lot
OpenStudy (anonymous):
If the points were negative then C would be the correct answer.
