Use slope formula: \[m = \frac{ y _{2}- y _{1} }{ x _{2}-x _{1} }\] Using the points: (-3 and 4) and (3,-4) \[y _{2}= -4, y _{1}= 4\]\[x _{2}= 3 , x _{1}= -3\]

Ok start with the top: what is -4 -4?
anonymous
  • anonymous
-8
anonymous
  • anonymous
why is that not right. looks good to me
anonymous
  • anonymous
And the bottom?
anonymous
  • anonymous
6
anonymous
  • anonymous
then isimplifed
anonymous
  • anonymous
i need the y intercept as well
anonymous
  • anonymous
Im sorry.. i forgot to reduce it.. you were right. It is -8/6, or -4/3
anonymous
  • anonymous
Then you need to use point slope form
anonymous
  • anonymous
oh
anonymous
  • anonymous
hmm
anonymous
  • anonymous
idk
anonymous
  • anonymous
\[y - y _{1}= m ( x - x _{1})\]
anonymous
  • anonymous
i know that
anonymous
  • anonymous
i dont know how to solve it
anonymous
  • anonymous
Now plug in the points and the slope
anonymous
  • anonymous
so
anonymous
  • anonymous
y-4=-4/3(x-3)
anonymous
  • anonymous
right
anonymous
  • anonymous
Which point did you use?
anonymous
  • anonymous
-3 and 4
anonymous
  • anonymous
(-3,4)
anonymous
  • anonymous
Ok for the last part, it would be x + 3 because of hte double negative
anonymous
  • anonymous
oh okay then wat
anonymous
  • anonymous
Now distribute the right side, and isolate the y
anonymous
  • anonymous
can u help me with it
anonymous
  • anonymous
Do you know how to distribute?
anonymous
  • anonymous
yes i got -4/3x-4
anonymous
  • anonymous
when i distrubute
anonymous
  • anonymous
Ok, now carry over the # on the left
anonymous
  • anonymous
what u mean can ushow me
anonymous
  • anonymous
y - 4 = -4/3x - 4 +4 +4 ------------------ Solve that
anonymous
  • anonymous
its o
anonymous
  • anonymous
Y-int, right?
anonymous
  • anonymous
yeah
anonymous
  • anonymous
Then you're done
anonymous
  • anonymous
thanks
