length
the distance between two points is length
11 points
Points: (-6, 1) and (-2, -2) Distance: 5 units
Points: (2, 2) and (8, -6) Distance: 10
the distance between 2 points
If you mean points of (-4, 2) and (1, 2) then the distance works out as 5
Points: (2, 4) and (5, 0) Distance: 5
Points: (4, 4) and (-2, -2) Distance: 6 times square root of 2
Displacement
(3-1)2 + (5-8)2 = 13 and the square root of this is the distance between the points
Points: (2, 1) and (14, 6) Distance: 13
Points: (-5, -2) and (3, 13)Distance works out as 17 units
