Remember, finding the distance is basically just finding the slope. So, if m = slope, then the formula is :
m = y₂-y₁ / x₂ - x₁
(-3,8), (-3,-8)
Simply plug in the values,
m = (-8 -8) / (-3 - (-3)
Simplify.
m = -16 / 0
So, m = 0
Next set of points.
(2,4) and (0,6)
m = 6 - 4 / 0 - 2
Simplify.
m = 2 / -2
m = -1
