Slope of a Line given points (-1, 2) and (3, -8)

Given Coordinates: x₁ = -1  y₁ = 2,  x₂ = 3  y₂ = -8
Slope Formula: m  =  
Substitute the given coordinates into the Slope Formula and Simplify:m  =  m  =  m  =  m  =  –
Therefore, the Slope of a Line given points (-1, 2) and (3, -8) is equal to  –

5/2

Note: As a decimal number,  –   = -2.5
