Only the second line!

If you can solve 1, then you can solve second one also..

point slope formula: (y2-y1) = m(x1-x2) solve for m by using the points (x1,y1) and (x2,y2) by plugging in the values for x1,x2,y1, and y2

i didn't line one is a different question lol

I know, but they are one and the same concept based question. If you can find the slope of first, then by using same formula, you can find second one too. :P

  • anonymous
i didn't the first line is the wrong problem (the next question)
anonymous
  • anonymous
Slope is given by: \[Slope = \frac{y_2 - y_1}{x_2 - x_1}\]

so 3/17?
anonymous
  • anonymous
How, show me first..
anonymous
  • anonymous
y2-y1 =3 ------- x2-x1= 17
anonymous
  • anonymous
Okay, what is y2 value and what is y1 value there?
anonymous
  • anonymous
-5 minus -8

In first point (-2,15), first is x1 value and second is y1 value. In second point (-8,-5), first is x2 value and second is y2 value..

Now plug in the values carefully..

-20 ---- -3 6.66666
Vocaloid
  • Vocaloid
not quite, check the denominator again
anonymous
  • anonymous
How you got -3 in denominator?
anonymous
  • anonymous
...
anonymous
  • anonymous
-6?
anonymous
  • anonymous
-5-15 = -20 this is okay.. Check your denominator once again.. -8 -(-2) = ??
anonymous
  • anonymous
-6?
Vocaloid
  • Vocaloid
yea, -6 is the denominator
Vocaloid
  • Vocaloid
so, what is the slope?
anonymous
  • anonymous
That is great..
anonymous
  • anonymous
10 --- 3
anonymous
  • anonymous
Good..
anonymous
  • anonymous
but i put - 10 ----- 3. so i failed you can't miss one :/
Vocaloid
  • Vocaloid
yup! 10/3 is the answer for the first problem do you think you can solve the second one on your own?
anonymous
  • anonymous
@Vocaloid this is second one.. :P
