Answer:
Part 1) [tex]LN=5.5\ units[/tex]
Part 2) [tex]MN=2\ units[/tex]
Step-by-step 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
[tex]LN=3-(-2.5)\\LN=3+2.5\\LN=5.5\ units[/tex]
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
[tex]MN=3-(1)\\MN=2\ units[/tex]
