Answer:
The coordinates of the mid-point of JL are (-5 , 2)
Step-by-step explanation:
If point (x , y) is the mid-point of a segment whose end-points are and
, then
and
∵ JL is a segment
∵ The coordinates of J are (-6 , 1)
∴ = -6 and
= 1
∵ The coordinates of L are (-4 , 3)
∴ = -4 and
= 3
Lets use the rule above to find the mid-point of JL
∵
∴ x = -5
∴ The x-coordinate of the mid-point is -5
∵
∴ y = 2
∴ The y-coordinate of the mid-point is 2
∴ The coordinates of the mid-point of JL are (-5 , 2)
