Line `L` has intercepts `aa n db` on the coordinate axes. When the axes are rotated through a given angle keeping the origin fixed, the same line `L` has intercepts `pa n dqdot` 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)`
