Question

Find the slope between two points : ( - 5,5 ) and ( 3, - 5 )

Answer 1

(-5,5)(3,-5)
slope = (y2 - y1) / (x2 - x1)
slope = (-5-5) / (3 - (-5)
slope = -10/(3 + 5)
slope = -10/8 = - 5/4 <== ur slope

Answer 2

Slope for (x₁, y₁) and (x₂, y₂):      (-5, 5) and (3, -5)

Slope:      (y₂ -y₁) / (x₂ -x₁)

Slope:      ( -5 - 5) / (3 - -5)  =  -10/8

Slope = -5/4 = -1.25
