    Equation

    The three Points A(-1,5), B(-7,7) and C(-1,1), and the circle that passes through them
    A)
    1 Find the slope of the line that passes through A and B.
    2 Find the coordinates of the midpoint of the line segment AB
    3 Find the equation of the perpendicular bisector of AB
    4 show that the line corresponding to the parametric equations
    x=t-4, y=3t+6
    is the same line as part A (3) above
    B)
    Find the equation of the perpendicular bisector of the line segment AC
    C)
    1 From Answer to parts (A)(3) and (B) , find the center of the circle that passes through A B and C
    2 Find the radius of this circle, giving your answer correct to two decimal places.
    3 Write down the equation of this circle
