We need to find the slope first so \[\frac{ y_2-y_1 }{ x_2-x_1 }\]
anonymous
  • anonymous
Can you find the slope using that formula please? ^_^

\[11\frac{ ? }{ ? }-8\]

oops sorry! 11 over -8

  • anonymous
Not quite I will set up the problem for you :) \[\huge~\rm~\frac{ -1-5 }{ -3-4 }=slope\]
anonymous
  • anonymous
-6 over -7?
anonymous
  • anonymous
yes :) Alright next step is to pick a point lets got with (4,5) Are you fimilar with this formula? \[\huge~\rm~y-y_1=m(x-x_1)\]
anonymous
  • anonymous
not really
anonymous
  • anonymous
\[\huge~\rm~y-y_1=m(x-x_1)\] M=slope=6/7<--lets keep it positive : ) x1=4 y1=5 Can you sub in the values please? :)

  • anonymous
5-5=6/7(4-4)
anonymous
  • anonymous
No quite we do not need to plug in the values for the varibles that have no number \[\huge~\rm~y-y_1=m(x-x_1)\] M=slope=6/7<--lets keep it positive : ) x1=4 y1=5 \[\huge~\rm~y-5=\frac{ 6 }{ 7 }(x-4)\]

I can finish up :) looks like they left

y+1=6/5(x+3) y+1=6/7(x+3) y-1=6/7(x-3) y+3=7/6(x+1)

oh ok the only problem is that they used the wrong point not hard to fix we always need to use the 2nd point so (-3,-1) and we get y+1=6/7(x+3) We get "+" because a negative and a negative touching each other make a postive :) understood?
