Hi,
Identify the slope-intercept form of the equation of a line which contains the points 
(–2, –1) and 
( 3, 4)  m = -5/-5 = 1    |{{{m =(y[2] - y[1])/(x[2] - x[1])}}}
Using the standard slope-intercept form for an equation of a line y = mx + b 
 where m is the slope and b the y-intercept.  
  y = x+ b    |Using ordered pair (3,4) to solve for b
  4 = 3 +b
  1 = b     Line is y = x+1
