if your given the midpoint= o,-3 and point A= 0,5 algebraically how do you find the other point?

Expert Answers

An illustration of the letter 'A' in a speech bubbles

Let the other point be (x,y)

Now, mid-point of (x,y) &(0,5) will be

[{(x+0)/2},{(y+5)/2}]

Given 

{(x+0)/2} = 0

thus, x = 0

Also, 

{(y+5)/2} = -3

or, y + 5 = -6

or, y = -11

Hence the required point (x,y) is (0,-11)
