Find the eq.n of the sides of a triangle having (4,-1) as a vertex, if the lines x-1=0and x-y-1=0are the equations of two int.bisectors of its angles?
The equations of two straight lines may be written in the matrix form as  (k       k-1 )(x)= (10)                  k-2  3k      y      20  , i) If the two lines do not intersect, find the value of k. ii) If k=3, find the point of intersection of the lines, using the inverse matrix method?
