Find the coordinates of the other endpoint when you are given the midpoint (point M) and one of the endpoints (point P).
P = (10, 6) and M = (-4, 8)

Answer:

The coordinates of the other end point  is  (-18,10).

Step-by-step explanation:

Let the coordinates of other point is Q(x,y)

⇒  M(-4,8)  is the mid point of P(10,6) and Q(x,y).

MID-POINT FORMULA states that for a mid point (a,b):

[tex](a,b) =( \frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )[/tex]

Applying the same mid point formula here, we get:

[tex](-4,8) =( \frac{10 + x}{2} , \frac{6+y}{2} )[/tex]

or, [tex](\frac{10+x}{2})   = -4 \implies  x = -8 -10 = -18[/tex]

and [tex](\frac{6+y}{2}  ) = 8 \implies  x = 16 -6 =  10[/tex]

or, (x,y) = (-18, 10)

or, the coordinates of Q is (-18,10)

Hence, the coordinates of the other end point  = (-18,10)
