What is the equations to find slop and y-intercept?

Question

aroub · Answer

there is a formula to find the slope... but if u want to find the slope and they y-intercept from a line then u use y=mx+b , where m is the slope and b is the y-intercept

aroub · Answer

this is the formula for the slope :
(x1.y1) and ( x2.y2) 

y2-y1/ x2-x1

amistre64 · Answer

the slope intercept equation is commonly denoted as: y=mx+b

anonymous · Answer

So if it was 2x+ 4y= 22 I would go
4+m(2)+b?

amistre64 · Answer

no; just algebra it to solve for y

amistre64 · Answer

and i did the math wrong .... just a little bit tho :)

amistre64 · Answer

2x+ 4y= 22 ;
/4   /4    /4
-----------
x/2 + y = 22/4  ; subtract off the x/2
-x/2         -x/2
--------------
         y = -x/2 +22/4

is better

amistre64 · Answer

if you want it more neater:

$$y = \frac{-2x+22}{4}$$
works fine

anonymous · Answer

is that all I have to do?

amistre64 · Answer

yes, the slope intercept form is simply; solve the equation for "y"
