anonymous · Answer

isn't there an equation to find this besides plotting the point on a chart?

skullpatrol · Answer

Yes. What does "slope" mean?

anonymous · Answer

slope would be well the angle of the slope in which a line travels across a cordinate plane?

anonymous · Answer

slope=(y2-y1)/(x2-x1)
  =(1-(-4))/(-2-3)
=(1+4)/(-5)
=5/-5
=-1

Why are you giving the answer away? @madrockz ???

anonymous · Answer

I think I remember doing that formula a while back

anonymous · Answer

wat is wrong in dat?

anonymous · Answer

(3, -4) and (-2, 1)

so...

(1 -(- 4) / (-2 - 3)

1 - (-4) = 5...
-2 - 3 = -5...

5/-5 = -1 :D

@madrockz  is the student learning anything?

anonymous · Answer

if the student wish to learn...he will first understand the steps and find out where he was wrong and get it corrected.

ohhh....ok u must have said dat in a polite manner

anonymous · Answer

I understand the formula now :)

skullpatrol · Answer

trial & error is not an efficient way of learning math

anonymous · Answer

Well it wasn't trial and error, i just forgot what the formula was, i completely understand the formula of (y2 - y1) / (x2 - x1) :)

anonymous · Answer

hey brad...have u understood my ans?i need to know ur opinion

anonymous · Answer

Yes I did

anonymous · Answer

ok thanks

skullpatrol · Answer

See if you understood what "slope" meant you would not have forgotten, right?

skullpatrol · Answer

Teaching MEANING is the most important thing...not formulas!

anonymous · Answer

I think I understand the meaning of a slope

anonymous · Answer

SWAG is watching me :o

skullpatrol · Answer

@Brad1996  what does it mean?

anonymous · Answer

To me slope is the angle of which a line travels on a cordinate plane.  The slope is showed normally by a fraction or whole number

skullpatrol · Answer

OK, what is negative slope?

anonymous · Answer

a negative slope is a slope thats on a downwards path.  Like the first cordinate is at 0,0 then the second one is at 5,-5

skullpatrol · Answer

What is the value for a vertical slope?

anonymous · Answer

x = 5 would be a vertical slope

anonymous · Answer

the x cordinate never changes and the line just goes straight up while the y value is free to change :)

skullpatrol · Answer

I asked you for the value of the slope.

anonymous · Answer

undefined is what your asking for?

anonymous · Answer

because I know that vertical lines slope is undefined and horizontal is 0

skullpatrol · Answer

Yes, undefined... also, what is the value of a horizontal slope?

anonymous · Answer

attachment

skullpatrol · Answer

But you have ONLY memorized them. Can you explain them to me?

anonymous · Answer

its 0 because a horizontal line is just going straight to the right or left.  It is not sloping at any angle which would make its value of slope 0

anonymous · Answer

Vertical is undefined because its just going straight up or straight down and has well a undefined slope lol

anonymous · Answer

I really need to get working again, been on this question for half an hour lol

anonymous · Answer

thanks for the help though :)

skullpatrol · Answer

Thanks for trying to understand :-)

anonymous · Answer

lol I got plenty more questions your more then welcome to help me understand them :)
