## Intersection of Circle and Line

The intersection points of a circle and a straight line are calculated.

### Example:

Circle and line :
¯¯¯¯¯¯¯¯¯¯¯¯¯
k : M(5|0) r = 5
g : x + y = 0
Intersection points :
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
S1(5|-5)
S2(0|0)

Circle and line :
¯¯¯¯¯¯¯¯¯¯¯¯¯
k : M(3|4) r = 5
g : 3x + 4y = 0
Point of tangency :
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
B(0|0)
