Final answer:
The length of AN is 13 units.
Step-by-step explanation:
To find the length of AN, we can use the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the coordinates of A (-4, -7) and N (1, 5), we have:
d = √((1 - -4)^2 + (5 - -7)^2)
d = √((1 + 4)^2 + (5 + 7)^2)
d = √(5^2 + 12^2)
d = √(25 + 144)
d = √169
d = 13
Therefore, the length of AN is 13 units.
