Answer:
(-3,-1)
Step-by-step explanation:
So we need to find a number, x=a, such that when we average that number and x=3, we get x=0.
Since we want x=0 to be middle and x=3 is 3 units right of 0, then we are looking for number 3 units left of 0 which is x= -3.
Since we want y=2 to be the middle and y=5 is 3 units above 2, then we are looking for a number 3 units below 2 which is y=-1.
The other endpoint is (-3,-1).
Let's average (-3,-1) and (3,5).
(-3+3)/2=0/2=0
(-1+5)/2=4/2=2.
