What is the distance between points N and M?
A. 4.2
B. 5.8
C. 11.9
D. 11.6

Answer:
Answer B is closest: 5.8 units
Step-by-step explanation:
Points M and N appear to lie in the same plane, so this problem is a 2-dimensional one. The distance along the x axis from N to the origin is 5 units and that along the y axis from the origin to M is 3 units. We apply the Pythagorean Theorem, as follows:
d = √(3² + 5²), or
d = √34, which is approximately 5.83 units. Answer B is closest: 5.8 units.
