Answer:
A = (0,-6)
B = (0,4)
C = (3,-9)
Step-by-step explanation:
Take the middle number of the x-coordinates.
A- The number in between 0 and 0 is 0
B- The number in between 2 and -2 is 0
C- The number in between -3 and 9 is 3
Take the middle number of the y-coordinates.
A- The number in between 0 and -12 is -6
B- The number in between 9 and -1 is 4
C- The number in between -3 and -15 is -9
You can also use the midpoint formula; M=(x(1) + x(2))/2 , (y(1) + y(2))/2
