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
