-----------
Find the slope, m
m = diffy/diffx = 5/2
---
(0,4) is the y-intercept
--> y = (5/2)x + 4

Hi,

(-2, -1) and 

( 0, 4)   m = %28-1-4%29%2F%28%28-2%29-0%29+=+%28-5%29%2F%28-2%29+=+5%2F2

***Using point-slope form, y+-+y%5B1%5D+=+green%28m%29%28x+-+x%5B1%5D%29 P(0, 4)

+y+-4=+green%285%2F2%29%28x+-+0%29

     y = (5/2)x + 4
