Final answer:
The distance between the points N(-1,-11) and P(-1,-3) is 8.
Step-by-step explanation:
The distance between two points can be found using the distance formula:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Using the given points N (-1,-11) and P (-1,-3):
Distance = sqrt((-3 - (-11))^2 + (-1 - (-1))^2)
Distance = sqrt(8^2 + 0^2)
Distance = sqrt(64 + 0)
Distance = sqrt(64) = 8.
