Step-by-step explanation:
Given circle has equation as
Center = P(0,0)
The point of contact of tangent = Q
Since tangent is perpendicular to the radius at the point of contact, we have
Slope = as slope of perpendicular to tangent
So tangent slope would be
-1/slope of this line
=
We have point on this line as given point
So using point slope form equation of tangent is
