the system k^L^ H- k2L2 = 0 obtained in this wayare called the three projecting planes of the line L± = 0, L2 = 0 onthe coordinate planes. ART. 24] SYSTEM OF PLANES THROUGH A LINE 27 Since two distinct planespassing through a line aresufficient to determine theline, two projecting planes ofa line… … 15) x = mz -f a, y = nz + b. (22) If the line is parallel to z = 0, the value of k for which the coefficient of x is made to vanish will also reduce the coefficient of y to zero, so that the projecting planes onx = 0 and on y = 0 coincide. Thisprojecting plane z =c and the projecting plane on z = 0…
