just plug in and solve
anonymous
  • anonymous
your y2 = 2.
anonymous
  • anonymous
your y1= 8
anonymous
  • anonymous
x2=11
anonymous
  • anonymous
x1= -2
anonymous
  • anonymous
just plug in and solve and you get the answer

  • Black_ninja123
\[\sqrt{11-(-2)^{2}+2-8^{2}}\]
Black_ninja123
  • Black_ninja123
\[\sqrt{169+36}\]
anonymous
  • anonymous
the slope is -6/13
Black_ninja123
  • Black_ninja123
\[\sqrt{205}=14.31\]
anonymous
  • anonymous
if your finding the slope then thats your answer
Jordans_openstudy
  • Jordans_openstudy
ohhh okay i think i am getting it now !
anonymous
  • anonymous
jords openstudy r u looking for slope?
anonymous
  • anonymous
or something else?
Jordans_openstudy
  • Jordans_openstudy
It says find the distance between and round to the nearest hundredth
anonymous
  • anonymous
if your looking for slope then thats your answer
Black_ninja123
  • Black_ninja123
He is not looking for the slope he is looking for the distance between the 2 points
Jordans_openstudy
  • Jordans_openstudy
Would that be the same thing or ? i am so bad at math lmao
Black_ninja123
  • Black_ninja123
Finding the slope is different
Jordans_openstudy
  • Jordans_openstudy
ninja would that be 14.31 as you gave me above?
Black_ninja123
  • Black_ninja123
yes but what is 14.31 nearest hundredth
Jordans_openstudy
  • Jordans_openstudy
14.30?

thx @geerky42
anonymous
  • anonymous
i forgot the ^2
geerky42
  • geerky42
Distance formula is in form of Pythagorean Theorem.
geerky42
  • geerky42
No problem

Do you know what this line is?
geerky42
  • geerky42
at x=1, y=1 at x=2, y=2 at x=3, y=3 and so on...
Jordans_openstudy
  • Jordans_openstudy
wait I'm confused
Jordans_openstudy
  • Jordans_openstudy
what do you mean on the second comment?
geerky42
  • geerky42
Never mind Any lines can be expressed as \(y = mx+b\), where \(m\) is slope and \(b\) is y-intercept. what is y-intercept here? Do you know?
Jordans_openstudy
  • Jordans_openstudy
Im really not so sure
geerky42
  • geerky42
y-intercept is where line intersect y-axis
geerky42
  • geerky42
where is this line intersect y-axis?

Jordans_openstudy
  • Jordans_openstudy
0
geerky42
  • geerky42
yeah, so b is 0. \(y = mx+0\) which is same as \(y = mx\) Now for m (slope), you know how to find slope?
geerky42
  • geerky42
\(\text{Slope} = \dfrac{\text{rise}}{\text{run}}\)
Jordans_openstudy
  • Jordans_openstudy
I forgot how to find the slope
geerky42
  • geerky42
For each "run", how much does it rise?

  • geerky42
Arrows are so small, sorry lol
Jordans_openstudy
  • Jordans_openstudy
no worries haha
Jordans_openstudy
  • Jordans_openstudy
is rise a ? or 2 ? hard to tell
