A light ray coming along the line 3x+4y=...

A light ray coming along the line `3x+4y=5` gets reflected from the line `a x+b y=1` and goes along the line `5x-12 y=10.` Then, `a=(64)/(115), b=(112)/(15)` `a=(14)/(15), b=-8/(115)` `a=(64)/(115), b=-8/(115)` `a=(64)/(15), b=(14)/(15)`

A

` a = 64/115 , b = 112/15`

B

` a = - 64/115, b = 8/115`

C

` a = 64/115 , b = 8/115`

D

`a = -64/115 , b = (-8)/115`
