If the boundary of the plane region determined by the system of inequalities x = 0, Y > = 0, (n > 0) is a triangle, and its If by the system of inequalities {x=0,(n>0) y>=0 If the boundary of the determined plane region is a triangle and the center of its circumscribed circle is on the x-axis, then the real number M=

The boundary of the plane region is determined by {Y > = 0, y = x-n},
If M > 0, the center of the circumscribed circle will not be on the X axis
Then M = x / M-N / m, and an edge is the diameter of circumscribed circle, and the corresponding angle is right angle
Then 1 / m * 1 / √ 3 = - 1,
m=-1/√3.
