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)
A tangent of a circle is a straight line that touches the circle at only one point.
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
Tangent
a tangent is a line that touches the circle at only ONE point
A tangent to a circle is a line from a point outside the circles which touches the circle at a single point.
A tangent of a circle is a straight line that touches the circle at only one point.

A striaght line , outside the circle, that just touches the circle in one place.
A tangent to a circle is a line from a point outside the circles which touches the circle at a single point.
A tangent of a circle is a straight line that touches the circle's circumference at just one point.
It is a straight line that touches the circle.
It is the tangent of the circle
A tangent is a line that touches a circle at exactly one point. It is perpendicular to the radius at the point of contact.
