Answer:
The coordinates of point L are (4.4 , -7.2) ⇒ answer A
Step-by-step explanation:
Assume that point L is (x , y)
Point L divides the line segment JK into two line segments such that
the ratio of JK to KL is 5 : 1
The coordinates of point J are (-10 , 12)
The coordinates of point K are (8 , -12)
∵
∵
Let = (-10 , 12) and
= (8 , -12)
and = JL : KL
∵ JK : KL = 5 : 1
∵ JK = JL + KL
∴ 5 = JL + 1
Subtract 1 from both sides
∴ JL = 4
∴ JL : LK = 4 : 1
∴ = 4 : 1
∵
∴
∴
∴ <u><em>The x-coordinate of point L is 4.4</em></u>
∵
∴
∴
∴ <u><em>The y-coordinate of point L is -7.2</em></u>
* The coordinates of point L are (4.4 , -7.2)
