Question

use the number line to find each measure.

1. ln
2. jl
3. kn
4. mn

Explanation:

Step1: Identify point coordinates

From the number line: $J=-4$, $K=-2$, $L=2$, $M=5$, $N=9$

Step2: Calculate LN: |N-L|

$\vert 9 - 2 \vert = 7$

Step3: Calculate JL: |L-J|

$\vert 2 - (-4) \vert = \vert 2 + 4 \vert = 6$

Step4: Calculate KN: |N-K|

$\vert 9 - (-2) \vert = \vert 9 + 2 \vert = 11$

Step5: Calculate MN: |N-M|

$\vert 9 - 5 \vert = 4$

Answer:

1. $LN = 7$
2. $JL = 6$
3. $KN = 11$
4. $MN = 4$
