Question

If line mn is the diameter of a circle with M(-3, -4) and N(-7, -14), find the center of the circle

Answer 1

the centre of the circle will be the midpoint of the diameter.

so find the midpoint of (-3, -4) and (-7, -14)

Answer 2

Midpoint:
\[(\frac{ x _{2} +x _{1}}{ 2 }, \frac{ y _{2} +y _{1}}{ 2 })\]
= ((-7-3)/2,((-14-4)/2)
= (-5,-9)

Answer 3

Center is (-5,-9)

Answer 4

why give the answer... just give the formula for the midpoint. Let the asker work through the information
