Two straight lines `u=0a n dv=0` pass through the origin and the angle between them is `tan^(-1)(7/9)` . If the ratio of the slope of `v=0` and `u=0` is `9/2` , then their equations are `y+3x=0a n d3y+2x=0` `2y+3x=0a n d3y+2x=0` `2y=3xa n d3y=x` `y=3xa n d3y=2x`

A

`y=3 xand 3y =2x`

B

`2y=3x and 3y =x`

C

`y+3x=0 and 3y+2x=0`

D

`2y+3x=0and 3y+x=0`
