Slope of a Line given points (-1, -1) and (2, -3)

Given Coordinates: x1 = -1  y1 = -1,  x2 = 2  y2 = -3
Slope Formula: m  =  
y2 − y1/x2 − x1

Substitute the given coordinates into the Slope Formula and Simplify:
m  =  
-3 − (-1)/2 − (-1)

m  =  
-3 + 1/2 + 1
m  =  
-2/3
m  =  –
2/3

Therefore, the Slope of a Line given points (-1, -1) and (2, -3) is equal to  –
2/3

Note: As a decimal number,  –
2/3
  -0.66666666666667
