cos y, which express thecoordinates of any point of the linein terms of the single variable d. If the straight line (1) containsthe point (x, y, z),x-x ^ y-y ^ z -z , cos a cos /8 cos yEliminate cos a, cos (3, cos y from (1) and (2) by division, andthe equation of the straight line through two… … Find the projection on the XY- 5, ?/ = 2 2 — 3 with the coordinate and YZ are 2 x + 3plane. 2. Find the intersections of xplanes. 3. Write the equations of the straight line through (2, 3,1), (- 1, 3, 5). 4. Write the equations of the straight line through the origin and thepoint (4, - 1, 2). 5.…
