Question

Derive the formula for the distance between two points x-2y+5 and x-2y+5 and hence find the distance between (2,-1,3) and (-2,1,3)

Answer 1

Answer:

x1 = 2 , x2 = -1 , x3 = 3

y1 = -2 , y2 = 1 , y3 = 3

use formula = x 1 +x2 + x3 / 3 , y1 + y2 + y3 / 3

Answer 2

Answer:

distance = x1 + x2 + x3 / 3 , y1 + y2 + y3 / 3
