Find the straight line equation which passes through point P (1,2) and makes the distance from a (2,3), B (0, - 5) equal

Find the straight line equation which passes through point P (1,2) and makes the distance from a (2,3), B (0, - 5) equal

(1) When a (2,3), B (0, - 5) are on the same side of the line, we get that the line AB is parallel to the line, K AB = 4, so the slope of the line is 4, Y-2 = 4 (x-1), which is reduced to 4x-y-2 = 0, so the line satisfying the condition is 4x-y-2 = 0, or x = 1
