The distance of the point `(2,3)` from the line `x-2y+5=0` measured in a direction parallel to the line `x -3y=0` is:
(A)  `2sqrt(10)`     (B)  `sqrt(10)`     (C)  `2sqrt(5)`     (D)   None of these

Text Solution

Verified by Experts

x-3y=0
m=1/3
`L_1:y-3=1/3(x-2)`
3y-9=x-2
3y-x=7-(1)
x-2y=-5-(2)
adding equation 1 and 2
3y-3y=7-5
