xy plane divides the line joining the points (2, 4, 5) and (−4, 3, −2) in the ratio
5:2
Given points are A(2,4,5) and B(−4,3,−2) Let xy plane divides the
line joining the points in the ratio of k:1
For x-y plane, z-coordinate must be zero
k(−2)+1(5)k+1=0
−2k+5=0
2k=5
k=52
So,xy plane divides the joining the points (2,4,5)
and (-4,3,-1) in the ratio of 5:2
