**How do I find the radius of circle when given a tangent line?**

Given the equation of the circle and the equation of the line, you can determine (and prove) the line is (or isn't) tangent to the circle by finding all points of intersection of the circle and the line. One intersection means tangent. None or more than one, not tangent.... The line which touches the given curve at a point(xo, yo), such that the slopes of the curve and line are equal, is called tangent line to a curve. Here is the tangent line graphing calculator for finding the equation of tangent line to circle for the given points.

22/02/2007Â Â· Best Answer: You can try using the equation of the circle (xÂ² + yÂ² = 4), solving for y and finding the derivative to get the slope, etc. But another method is to realize that the tangent line of a circle is going to be perpendicuar to the radius at that same point. This means that the origin, the tangent...The line which touches the given curve at a point(xo, yo), such that the slopes of the curve and line are equal, is called tangent line to a curve.

- 8/06/2010Â Â· Best Answer: The tangent line has a slope of -1/2, so the perpendicular radius will have a slope of -1 / (-1/2) = 2 So we're looking for a line of slope 2 that passes through our center point. 11 - 2(4) = 3, so that line would be y=2x+3 So, to find the point on the circleâ€¦
