Examples -> Geometry -> Two-dimensional geometric shapes -> Circle

There are two points on the coordinate plane: A (2; 6) and B (4; -2).
a) Write the equation of the perpendicular to the section AB.
b) Write down the equation of the circle centered on A through B.
Given y equals is a 3 x straight line and x2+8x+y2-4y=48 a circle.
c) Give the coordinates of the line and the circle with their coordinates.
