1. Suppose that during its flight, the elevation e (in feet) of a certain airplane and its timet
in minutes since takeoff, are related by a linear equation. Consider the graph of this
equation, with time represented on the horizontal axis and elevation on the vertical
axis. For each situation, decide if the slope is positive, zero, or negative.
a. The plane is cruising at an altitude of 37,000 feet above sea level.
b. The plane is descending at rate of 1000 feet per minute.
c. The plane is ascending at a rate of 2000 feet per minute.

Answer:

A:zero

B:negative

C:positive

Step-by-step explanation:

the key words just tell you for A it was cruising B it was negative because descending and C is positive because ascending.

The correct explanation for the slope will be;

a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.

b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.

c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.

What is mean by Slope?

The slope of line is a measure of its steepness.

Given that;

During its flight, the elevation e (in feet) of a certain airplane and its time

in minutes since takeoff, are related by a linear equation.

In the graph, time represented on the horizontal axis and elevation on the vertical axis.

Now,

a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.

Because the plane is cruising.

b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.

Because the plane is descending.

c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.

Because the plane is ascending.

Thus, The correct explanation for the slope will be;

a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.

b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.

c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.
