\[y- y1 = m(x-x1) \] I know the formula
anonymous
  • anonymous
First find slope \[m=\frac{ (y2-y1) }{ (x2-x1)}\]
anonymous
  • anonymous
\[m=\frac{ \left( y_2 - y_1 \right) }{ \left( x_2 - x_1 \right) }\] this will get you the slope and... \[y-y_1 = m \left( x-x_1 \right)\] is the point slope form of a line

Slope is 3?
anonymous
  • anonymous
slope = rise/run... how far must you go in the x direction to get from 1 to 12? that's your run. how far must you go in the y direction to get from 0 to 9? that's your rise. divide the rise by the run to get the slope.

I already found the slope it's 3 right?
anonymous
  • anonymous
nope
anonymous
  • anonymous
wtf o-o?
anonymous
  • anonymous
It's not 3?
anonymous
  • anonymous
use the formula... see what you get.

-.- Getting 3
anonymous
  • anonymous
(1,0) and (12,9) right?
anonymous
  • anonymous
m= (9 - 0)/(12 - 1) = 9/11 how is this 3?
anonymous
  • anonymous
Ohh my bad y2-y1, x2-x1
anonymous
  • anonymous
no worries.
anonymous
  • anonymous
y-y1=m(x-x1)
anonymous
  • anonymous
\[y-0=\frac{ 9 }{ 11 }(x-1) ?\]
anonymous
  • anonymous
there you go!
