Question 604821
Just checking to see if I did this problem correctly. 
Find the equation of the line that goes through the points (-4,1) and (-1,4)
============
I found the slope of -1/-1 or -1 ************* -1/-1 = +1
------------
y = mx + b
4 = 1*-1 + b
b = 5
--------
y = x + b
4 = -1 + b
5 = b 
answer y = x + 5 Is correct.
