Ehh math help T^T

[Kappy]

dunno if this is the right place or thread for this but oh well :|

i never heard of slope in my life i have a certain amount of days before i get an F in math class. which i already have.


could anyone tell me what it means to find the slope, y-intercept, and equation for a line? :/

but dumb it down ._.

try that. its like youtube, but for school lol or u could find some stuff on utube too but lol
i could explain it to ya too lol

try searching for what you're looking for on there or on youtube

 

[Kappy]

crap, its blocked on my school labtop :/

ill just make up something or skip it then watch the answers tomorrow then ask for help T_T

 

[Akiza]

well thats strange...
well then...to get y, u gotta put it by itself in this form of a linear equation, the slope intercept form of an equation: y=mx+b. y is your y coordinate (not intercept) (in (x,y)), m is ur slope (rise/run (up+/down- over left-/right+)), x is your x coordinate (in (x,y)) and b is ur y intercept.

to find your y intercept (b), you put ur y interval and ur x interval and ur slope in the equation, and solve for b. for example, if ur coordinates are (8,7) and ur slope is +3, to find ur y intercept you:
y=mx+b
7=3(8)+b
7=24+b
7-24=b
-17=b
and thats your y intercept.

to get ur slope is to place ur rise (up+/down-) over ur run (left-/right+) and solve it. like if ur rise is +4, and ur run is +2, your rise/run is 4/2 = 2, which is ur slope.

and slope intercept form of a linear equation i explained in the first part.

 

[Kappy]

i got lost at the +3
its passed my bed time and im going to bed.. ill look it over in the morning..
thanks.

 

[Akiza]

well after the +3 i explained as best i could how to solve for b, using only typing anyways....slope was the next thing i tried explaining...ah well gl with it

 

[sabbyxx]

y= slope x + y-intercept

remember rise/run when it comes to slope

 

[Typhon]

slope = (y2-y1 / x2-x1)

So basically what you're doing is analysing the components that make up the equation of a line.

It's pretty simple actually.

The equation for any straight line is y= mx + b

The slope is the 'm' part of the equation. In other words the slope is the gradient of the line.
The y-intercept is the 'b' part of the equation. This is where the line crosses the y axis.

So to find the equation of any line all you need is a point on that line [which is where you get the (x,y)] and the gradient/slope -> (m)

This equation is y= ½x +2

The slope in this equation is ½

The y-intercept is 2.

To find your slope [m] you can do it in two ways.
Rise
-----
Run

or if you have two points: y2-y1 / x2-x1

Example:

.................................x1,y2 and x2,y2
Here the two points are (0,5) and (2,0)

so the slope of this line would be
0-5 divided by 2-0 which is equal to -2.5.


Hmm i think that's about it.
Do tell if you have any questions.

Very detailed explanation

xd

You should have asked me on msn Yoko...i had to study this for the whole summer :| and i pretty sure know every part of it... IT IS BURNED INSIDE MY BRAIN!!!!

 

[Gatsndshanks]

I feel like an idiot cuz i do not understand a single word of this (or number)

No need to worry...well actually if i said u were i would probably get banned :|:|:|

Thats why i am ass-kissing u xd

LOL
Just joking...actually i didn`t know anything 2 months ago too...it looked like chinese to me :|

 

[Kappy]

thanks you guys for helping me and Lawliet helped a lot sorry to say U_U
i actually get it!! O_O
Ahh! now i can bring my F up to a C ._.

 

[Faceless]

Bloody hell, I try to run away from Math, but its following me wherever I go, even on NB O_O

 

[Kappy]

haha! xd
my teacher teaches me this to fast and shes to hyper for me. i cant do all of this work so fast like her other students who already knows it.

From what I remember, Slope is a fraction that represents a pattern in a graph. You need to find a Y= equation to calculate the slope.

that slightly helps ._.

Not more than usual.
Though I could say the same thing about myself.

 

[RikaSatomi]

if you think slopes is hard, what till you get to calculus. this stuff is a bi*ch.
