+ 2gx + 2fy + c =
0 be perpendicular to each other.
2. Find the length of the chord intercepted by the circle x2 +y2
– x + 3y – 22 = 0 on the line
y = x -3
3. Show that x2
+ y2
+ 2lx + 4 = 0; x2
+ y2
+ 2my - g = 0 Circles intersect each other
orthogonally.
4. Find the vertex and focus of x2
–6x–6y+6 = 0.
5. If 3x – 4y + k = 0 is a tangent to x2
