<u>ANSWER:</u>
The characteristics that are used to describe air are:
- Density
- Mass
- Pressure.
<u>EXPLANATION:</u>
- The density of air differs from one place to another so density characterizes the characteristics of air on that place.
- Similarly, pressure and mass also determines the characteristics of air. In normal temperature and pressure the air has the pressure of 1atm and density of
- In this way air is characterized by the density, pressure and mass.

The answer is below
Explanation:
The question is not complete, the coordinates of K and M are not given. Let us assume The coordinates are at K(1, -6) and M(9,-2)
Answer: If a line segment AB with coordinates at is divided by a point O(x, y) in the ratio n:m, the coordinates of point O is given by the formula:
K(1, -6) and M(9,-2) are divided in ratio 1:3 by point L. Let us assume L is at (x,y), hence the coordinate of point L is given as:
Point L is at (3, -5)
