Circle equation: x^2 +y^2 -8x -16y -209
Completing the squares: (x-4)^2 +(y-8)^2 = 289
Centre of circle: (4, 8)
Radius: 17
Slope of radius: 0
Tangent equation line: x = 21 passing through (21, 0)

Tangent of a circle is what?
A tangent of a circle is a straight line that touches the circle at only one point.
What is the tangent equation of the circle 2x squared plus 2y squared -8x -5y -1 that touches the point of 1 -1 on the Cartesian plane?
If you mean: 2x^2 +2y^2 -8x -5y -1 = 0 making contact at (1, -1) Then the tangent equation in its general form works out as: 4x+9y+5 = 0
