Slope of a Line given points (-1, -1) and (4, -1)

Given Coordinates: x₁ = -1  y₁ = -1,  x₂ = 4  y₂ = -1
Slope Formula: m  =  
Substitute the given coordinates into the Slope Formula and Simplify:m  =  
m  =  m  =  
m  =  0
Therefore, the Slope of a Line given points (-1, -1) and (4, -1) is equal to 0
Note: Since y₁ = y₂ (-1 = -1), the slope of the line is equal to 0 (m = 0)
