Step-by-step explanation:
In 2x + 3y + 5 = 0,
the constant 5 should be taken to the RHS of the equation, that is 2x + 3y = -5
Dividing both sides with √(a2 + b2) = √(22 + 32) = √13, we get To make the RHS positive,
we multiply both sides with (−1).
Thus, the normal form is where cos α = -2/√13 and sinα = -3√13
Now, the distance of the line from the orgin is
p=c/root a^2+b^2= -5 by root 13 =5 by root 13
