In a certain country, the heights and depths of a road are measured in relation to sea level. sea level has a value of 0. the lowest point of the country lies at −9 feet. the highest point of the country lies at +108 feet. which of the following statements best describes the lowest and the highest points?

1. the lowest point is 9 feet below sea level, and the highest point is 108 feet above sea level.
2. the lowest point is 9 feet above sea level, and the highest point is 108 feet below sea level.
3. the lowest point is 9 feet below sea level, and the highest point is 108 feet above the lowest point.
4. the lowest point is 9 feet above sea level, and the highest point is 108 feet below the lowest point.

1. The lowest point is 9 feet below sea level, and the highest point is 108 feet above sea level.

Step-by-step explanation:

The sea level is considered to be zero levels.

Now, the level +x feet means it is at x feet higher than sea level and the level -x feet means it is at x feet lower than the sea level.

Now, the lowest point of the country lies at −9 feet. The highest point of the country lies at +108 feet.

That means, the lowest point is 9 feet below sea level, and the highest point is 108 feet above sea level. (Answer)

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
