-3,-8 and 3,-2?????
TuringTest
  • TuringTest
did you try to apply the formula we just showed you yet?
TuringTest
  • TuringTest
\[slope={y_2-y_1\over x_2-x_1}\]

i forgot witch was witch
TuringTest
  • TuringTest
whaddya mean?
anonymous
  • anonymous
witch is y2 and y1 and x2-x1
TuringTest
  • TuringTest
ordered pairs are almost always written\[(x,y)\]which one is \[(x_1,y_1)\]and which is \[(x_2,y_2)\] does not matter, you will get the same answer both ways
TuringTest
  • TuringTest
so let\[(x_1,y_1)=(-3,3)\]then what is\[(x_2,y_2)\]? once you identify that, just plug the corresponding variables into the formula

-3,-8?? and 3,-2??
TuringTest
  • TuringTest
where did you get those numbers and what do they mean?
anonymous
  • anonymous
ugh nvm ill just skip this question
TuringTest
  • TuringTest
why? this is essential; if you are to be able to solve the problem the rest will be much easier,. just be patient and learn this please
TuringTest
  • TuringTest
start super basic you been given have two points: what are they?
anonymous
  • anonymous
-3,3 and -8,-2
TuringTest
  • TuringTest
yes, but please write them with parentheses so we know what they are (-3,3) and (-8,-2) now you pick: which do you want to be point 1 ? i.e \((x_1,y_1)\) ? (it makes no difference just choose one)
anonymous
  • anonymous
yes
TuringTest
  • TuringTest
yes what?
TuringTest
  • TuringTest
which point do you choose to be point \((x_1,y_1)\) ?
anonymous
  • anonymous
what wud be x1 and y 1 witch numbers
anonymous
  • anonymous
im not sure...
TuringTest
  • TuringTest
pick one, your choice makes no difference
anonymous
  • anonymous
cud (-3,-8) be x1 and y1
TuringTest
  • TuringTest
no because that's not a point given your choices are: (-2,-8) and (-3,3) just pick one
anonymous
  • anonymous
(-2,-8)
TuringTest
  • TuringTest
okay, so what is \(x_1\) ? what is \(y_1\) ?
anonymous
  • anonymous
-2x1 and -8 y1????
TuringTest
  • TuringTest
yes to write it correctly we should write x1=-2 and y1=-8 so what then must be point (x2,y2) ?
anonymous
  • anonymous
(-3x2 and 3y2
TuringTest
  • TuringTest
x2=-3 y2=3 yes, but again please use the right notation, otherwise we get confused easily
TuringTest
  • TuringTest
so now you know that\[x_1=-2\]\[y_1=-8\]\[x_2=-3\]\[y_2=3\]so now just plug those numbers into the formula for the slope
anonymous
  • anonymous
wud it be m=3-(-8) ------- -3-(-2)
TuringTest
  • TuringTest
yes!!!!!!!!
TuringTest
  • TuringTest
now simplify :)

11/-1
anonymous
  • anonymous
?
TuringTest
  • TuringTest
also known as -11 yes, great job :)
TuringTest
  • TuringTest
so now you don't have to ask about how to find slope between two points anymore, because you know how to do it saves time for both us and you ;) again, thank you for sticking with me, I hope you understood the process
anonymous
  • anonymous
will you help me with find the x intercept?
TuringTest
  • TuringTest
Sorry, I gotta take a break, but post separately and someone will help you or maybe me when I can.

  • anonymous
ok thanks
