The line equation is $\"\"$ .

Find the point that lies on the line.

Consider the point be $\"\"$ and it is closest to the origin $\"\"$ .

Hence the point is $\"\"$ .

The distanc between the point and the origin is

$\"\"$

The diatance is closest to origin when its first derivative becomes zero.

Apply derivative on each side with respect to $\"\"$ .

$\"\"$

$\"\"$ .

Equate $\"\"$ to zero.

$\"\"$

Substitute $\"\"$ in $\"\"$ .

$\"\"$

Therefore the point lies on the line which is closest to origin is $\"\"$ .

The point lies on the line which is closest to origin is $\"\"$ .
