The attempt at a solution first i find AB which is (2,2,-2) the equation if line is then (1,0,-1)+λ(2,2,-2) i made it so that λ is 0.5, which then OM is (2,1,-2), as its the mid point. i found AC to be (3,-3,3) the equation of AC is (1,0,-1)+λ(3,-3,3) which then i made lambda to be 1/3...but is this the right working? i did that and i cant get the awnser.
