(1.0, 228,000), (3.0, 204,000) If I have these numbers to work with, how do I figure out the slope-intercept

Question

amistre64 · Answer

( x   ,    y ) 

  (3.0, 204000)
-(1.0, 228000)
-------------
  ( 2  ,  -24000 )  slope = y/x  = -12000

anonymous · Answer

That is what I got, but I am having trouble with the slope-intercept of the problem it does want to work

anonymous · Answer

Can you tell me what numbers to plug in where. y=m(x)+b

amistre64 · Answer

if my computer behaves :)

Thanks

amistre64 · Answer

y =      mx      +     b
|           |                |
y = -12000 x + 240000

anonymous · Answer

where did the 240,000 come from

amistre64 · Answer

i plugged in an easy pointt from above: (1,228000)

228000 = -12000(1) + B

 228000
+12000
--------
240000 = B
