Question

5. What is the length of LN?

6. What is the length of MN?

Answer 1

Part 1)
`LN=5.5\ units`

Part 2)
`MN=2\ units`

Explanation:

Part 1) What is the length of LN?

To find out the length LN subtract the coordinate of L from the coordinate of N

so

`LN=3-(-2.5)\\LN=3+2.5\\LN=5.5\ units`

Part 2) What is the length of MN?

To find out the length MN subtract the coordinate of M from the coordinate of N

so

`MN=3-(1)\\MN=2\ units`
