Questions
The line passing through the points crosses the plane at the point then
a
a=2,b=8
b
a=4,b=6
c
a=6,b=4
d
a=8,b=2
detailed solution
Correct option is C
The yz- plane cuts the line segment joining the points Ax1,y1,z1,Bx2,y2,z2in the ratio−x1:x2Hence, the yz-plane divides the line segment joining the points 5,1,a,3,b,1in the ratio 5:3externally Hence the point of division is 0,5b−32,5−3a2=0,172,−132Equate the corresponding coordinates, we get a=6,b=4Talk to our academic expert!
