Answer :
Given:
Line 
To find:
The perpendicular distance from the origin of the perpendicular from the point (1, 2) upon the straight line 
.
Concept Used:
Distance of a point from a line.
Explanation:
The equation of the line perpendicular to 
is 
This line passes through (1, 2).
∴ 
+ 2 + λ = 0
⇒ λ 
Substituting the value of λ, we get 
Let d be the perpendicular distance from the origin to the line 
d
Hence, the required perpendicular distance is
