Question

point p (0,-7) is the point of intersection of y axis and perpendicular bisector of the line segment joining the points A (-1,0) and B (7,-6). justify​

Answer 1

Point P(0,-7) is the point of intersection of y axis and the perpendicular bisector of the line segment joining the points A(-1,0) and B(7,-6) ... Hence point lies on the perpendicular bisector of the midpoint of AB. In the point , coordinate is 0, hence the point lies on y-axis too.
