Robin Sahni 7 years, 11 months ago

(1,1,-1) (6,4,-5),(-4,-2,3) Equation of a plane passing through point (1,1,-1)is,. A(x-1)+B(y-1)+C(z+1)......Put this as eq.{1}------ Now the plane,{1} passes through the points (6,4,-5) &(-4,-2,3).... A(6-1)+B(4-1)+C(-5+1).=5A+3B-4C. Put it as {2}.... Then A(-4-1)+B(-2-1)+C(3+1).= -5A-3B+4C...Put it as eq. {3}. Solve eq. {2} & {3} by cross multiplication method.......A/12-12=B/20-20=C/-15+15.......And A/0= B/0=C/0.... So the points are collinear points.
