Hi
Using the point-slope formula, {{{m =(y[2] - y[1])/(x[2] - x[1])}}}
(-3,-5) 
(-7,-6)  m = [ -5-(-6)[  / [-3 -(-7)] = 1/4
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 = (1/4)x + b  |using ordered pair Pt(-3,-5) to solve for b
-5 = (1/4)*-3 + b
 -20/4 = -3/4 + b
  -17/4 = b
 y = (1/4)x -17/4
