Question

The midpoint of XY is point M (-12,5) if the coordinates of x are (3,-3) what are the coordinates pf y

Answer 1

Answer:

The midpoint of XY is point

M(�12, 5). If the coordinates

of X are (3, �3), what are the

coordinates of Y ?

----

Each coordinate of the midpoint is the average

of the corresponding endpoint coordinate.

----

Solve:

Let the coordinates of Y be (x,y)

---

(3+x)/2 = -12

3+x = -24

x = -27

----

(-3+y)/2= 5

-3+y=10

y = 13

---

Coordinates Y: (-27,13)
