The coordinates of point J are(-7,2) , and the midpoint of JK is at L(3,5). What are the coordinates of point K?
svlad2 [7]

Answer:

C. (13,8)

Step-by-step explanation:

<u>Midpoint formula is (x²+x¹</u><u> </u><u>/2 , y²+y¹</u><u> </u><u>/2 )</u>

Midpoint= L(3,5)

J(-7 , 2) ; K(x , y)

(3,5) = (x+-7 /2 , y+2 /2)

x-7 /2 = 3

x-7 = 6

x= 13

y+2 /2 =5

y+2 = 10

y= 8

Therefore K is K(13, 8)
