Question

Find an equation for the circle that has center (-1, 4) and passes through the point Find the center and radius of the circle with equation x^2 + y^2 -6x + 10y + 9 = 0. center radius Let A(-7, 4) and B(5, -12) be points in the plane. Find the slope of the line that contains A and B. Find an equation of the line passes through A and B. y = What are the intercepts? Find the midpoint of the segment AB. Find an equation of the perpendicular bisector of AB. Find an equation of the circle for which AB is a diameter. If you have had difficulty with these problems, you may wish to consult the Review of

1st question already solved

2)    x^2 +y^2 -6x +10y +9 =0

(x^2 -6x) +( y^2 +10y ) +9 =0

(x-3)^2 -9 + (y +5)^2 -25 +9 =0

(x-3)^2 +(y+5)^2 = 25

Centre ( 3 , -5) and radius = 5 units
