Line L has intercepts a and b on the co-...

Line L has intercepts a and b on the co-ordinate axes. When the axes are rotated through a given angle keeping the origin fixed, the same line L has intercepts p and q, then

A

`a^2 +b^2 =p^2 +q^2`

B

`1/(a^2)+1/(b^2)=1/(p^2)+1/(q^2)`

C

`a^2 +p^2 =b^2 +q^2`

D

`1/(a^2)+1/(p^2)=1/(b^2)+1/(q^2)`
