We are given skew lines a and b. a:x=12t,b:x=13s,y=2+3t,y=2s,z=4+2t; tR,z=22s; sR. Find parametric equations of a straight line p, that is intersecting both lines a and b and lying in the plane 2x+3yz8=0.
p:x=9+r,y=10+r,z=4+5r; rR
p:x=92r,y=102r,z=4+10r; rR
p:x=910r,y=10+9r,z=4r; rR
p:x=9+2r,y=10+2r,z=42r; rR
