Answer:
21
Step-by-step explanation:
5(4)+1=20+1=21
Given:
J (-2,3), K(6,5), L(0,7) and N(4,1).
Note that the midpoint of a line connecting the two points (x₁,y₁) and (x₂,y₂) is
(x,y), where
x = (x₁ + x₂)/2
y = (y₁ + y₂)/2
Calculate the midpoint for line JK.
x = (-2 + 6)/2 = 2
y = (3 + 5)/2 = 4
The midpoint of line JK is (2, 4).
Calculate the midpoint of line LN.
x = (0 + 4)/2 = 2
y = (7 + 1/2 = 4
The midpoint of line LN is (2, 4).
The midpoints for lines JK and LN are the same.
Answer:
Lines JK and LN have the same midpoint.
