Points A (3,1), B(-1,-11), C(-5,9)

what the slope that passes through A and B

whats the co-ordinates of the midpoint of the line segment AB

whats the equation of the perpendicular bisector of AB

?? show that the line corresponding to the parametric equations

x = t - 14

y = -1/3t

is the same as the perpendicular bisector of AB

what is the equation of the perpendicular bisector of the line segment AC

from the answers of the above find the centre of the circle that passes through a b c

whats the radius of this circle

what the equation of this circle

any help to any of the above would be extremely appreciated
