Well, okay. So let me graph the fine y=3x first.|dw:1328654808387:dw|

did you know my bro is smart? man is soooooo smart!! he rox the house!

ok...

Now let me draw the line y= 3x +10 |dw:1328654980379:dw|
saifoo.khan
  • saifoo.khan
Now, combine them: |dw:1328655032021:dw|

What difference can u spot?

Amistre boss is here. :D It's like u called 911 for help.

so y = -1/3x
amistre64
  • amistre64
yep; now find where it crosses at to establish 2 points
amistre64
  • amistre64
(0,0) is one point
anonymous
  • anonymous
crosses where?
amistre64
  • amistre64
the parallel lines ...
amistre64
  • amistre64
y = -1/3 x y = 3x -1/3 x = 3x when x = ?
amistre64
  • amistre64
y = -1/3 x y = 3x + 10 -1/3 x = 3x+ 10 when x = ?
anonymous
  • anonymous
is -3,1 a point?
amistre64
  • amistre64
maybe, lets see :) -1/3 * -3 = 1 -9 + 10 = 1 looks good to me
amistre64
  • amistre64
so the distance between 0,0 and -3,1 is?
anonymous

anonymous
  • anonymous
is that right??
anonymous
  • anonymous
square root of 37?
amistre64
  • amistre64
i think you got alittle to excited on that one
amistre64
  • amistre64
(-3,1) ^2 = 9, 1 9+1 = 10 sqrt(10)

  • anonymous
oops

  • anonymous
ok, but i think i understand now. Thanks
amistre64
  • amistre64
yay!! :)
saifoo.khan

amistre64
  • amistre64
i always sleep in class lol

Haha.

May you check this? y = x + 3 y = x -1 the answer is the square root of 8?
saifoo.khan
  • saifoo.khan
Try posting this on left with @Amistre.. He will check it. :0
