Question

J is the midpoint of HK, H has coordinates (3,−2), and J has coordinates (5,5). Find the coordinates of K.

The coordinates of K are

Answer 1

Explanation:

H (3,-2 )..........J (5,5)...........K (x, y)

5=(3+x)/2

10=3+x

x=7

5=(-2+y )/2

10=-2+y

y=12

coordinates of k (7,12)

Answer 2

Formula: M = (x1+x2/2)=x,(y1+y2/2)=y

Find the x-coordinate.

(x1+5/2) = 3

x1 + 5 = 3

x1 = -2

Find the y-coordinate.

(y1+5/2) = -2

y1 + 5 = -4

y1 = -9

Therefore, the endpoint is (-2, -9)

Best of Luck!
