Answer:

Correct choice (6,7)

Explanation:

The center of the circle is the midpoint of the diameter. Let the unknown enpoint of the diameter be point with coordinates (x,y). If the center of a circle is (4, 6), and an known endpoint of a diameter is (2, 5), then


(x+2)/(2)=4\Rightarrow x+2=8,\ x=8-2=6,\\ \\(y+5)/(2)=6\Rightarrow y+5=12,\ y=12-5=7.

You get the point (6,7).
