Let (x + 3) * 2 + (y + 5) * 2 = R * 2 have only one point and the distance from the point to the line 4x-3y + 2 = o be 1, then the radius of the circle R is 1 Change only one point to only two points

Let (x + 3) * 2 + (y + 5) * 2 = R * 2 have only one point and the distance from the point to the line 4x-3y + 2 = o be 1, then the radius of the circle R is 1 Change only one point to only two points

The distance from the center of the circle (3, - 5) to the straight line is 5
There are two lines 4x-3y-7 = 0 and 4x-3y + 3 = 0 whose distance is 1 from the line 4x-3y-2 = 0
The distance from the center of the circle to 4x-3y-7 = 0 is 4, and the distance to 4x-3y + 3 = 0 is 6
If the circle intersects with 4x-3y + 3 = 0, then the circle must intersect with 4x-3y-7 = 0, and the number of intersections is more than two, so there are more than two points on the circle whose distance from 4x-3y-2 = 0 is equal to 1, so the circle does not intersect with 4x-3y + 3 = 0
If the distance between the circle and 4x-3y-7 = 0
