Paper 2Geometry

The line segment joining the points (2,2)(2,2) and (6,4)(6,4) is a diameter of a circle.

This circle is translated by 2 units in the negative xx-directions, then reflected in the xx-axis and then enlarged by a scale factor of a 12\dfrac12 about the center of the resulting circle.

A(x+2)2+(y−3)2=20(x+2)^2+(y-3)^2=20
B(x−2)2+(y+3)2=54(x-2)^2+(y+3)^2=\dfrac54
C(x−2)2+(y−3)2=5(x-2)^2+(y-3)^2=5
D(x−2)2+(y+3)2=80(x-2)^2+(y+3)^2=80
E(x+2)2+(y−3)2=25(x+2)^2+(y-3)^2=25
