Question 1185124: Solve all parts of following question:
1- Find the equation of the straight line passing through origin and perpendicular to the line +2x%5E2+-+5xy+%2B+y%5E2+=+0+?
2- Find the equation of the straight line passing through point (5, -4) which cuts the intercept 5 between two parallel lines +y+=+%28-1+-+x%29%2F2+ and +y+=+%281+-+x%29%2F2+?
3- What is the name of the curve in which angle between tangent and radius vector at each point is one half of the vectorial angle? Explain this with diagram.

1 - Regarding part  (1),  notice that the given equation describes  TWO  straight lines passing through the origin.

      So,  it becomes  UNCLEAR  to which one of the two lines the perpendicular line should be plotted
      and the corresponding equation should be written.


2 - Regarding part  (2),  could you explain  PLEASE  the meaning of this passage 

        the straight line passing through point (5, -4) which cuts the intercept 5 between two parallel lines +y+=+%28-1+-+x%29%2F2+ and +y+=+%281+-+x%29%2F2+?

   which seems to be non-sensical.
