rather than taking the long route and finding the point of intersection of the line with the mirror, you can instead use a clever trick. simply find the reflection of the point  (3,10) in The Mirror 2 X +3y -6=0. lets call the reflection as point C. then write the eqn of line joining point C and (7,2). and there you have it, equation of the reflected Ray!
