Hi
Find a general form equation for the line through points (-2,-3) and (8,-1)
Using the point-slope formula, {{{m =(y[2] - y[1])/(x[2] - x[1])}}}
(-2,-3) 
 (8,-1)  m = -2/-10 = .2
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 = .2x + b
 -3 = -.4 + b
   -2.6 = b
 y = .2x -2.6
