Question

anonymous · Answer

equation*

anonymous · Answer

that is the equastion/

anonymous · Answer

find slope and then solve for b

anonymous · Answer

idk

anonymous · Answer

follow along :P

kayy gooo

anonymous · Answer

y2 - y1 
m = ------
        x2 - x1 

        -16 - 12
m = -------
         -4 - 3 

       -28 
m =   --
         -7 

m = 4

anonymous · Answer

thats slope

anonymous · Answer

y = mx+b 

use any coordinate 
12 = 4(3) +b 
12 = 12 + b 
12 - 12 = b 
0 = b 

y = 4x

anonymous · Answer

So that would be the equastion ^ ^

anonymous · Answer

yeah :)

anonymous · Answer

thanks okay can you show me how to do this one. but step by step  (-3,7 ) and ( 6,-8 )

anonymous · Answer
