The graph shows the altitude of a bird overtime.
what is the slope of the line and what does it mean in this situation?
•the slope is -500. this means that the bird descends 500 m each minute.
•the slope is -350. this means that the bird descends 350 m each minute.
•the slope is 350. this means that the bird ascends 350 m each minute.
•the slope is 500. this means that the bird ascends 500 m each minute.

For this case we have a graph that represents the altitude of a bird as a function of time. We must find the slope of the graph and explain its meaning in this context. By definition, you must know at least two points of a line to find its slope, since it is given by:

Where:

From the graph we observe the points:

Substituting in the formula of the slope we have:

This means that the bird descends 500m per minute.

The slope is -500. This means that the bird descends 500 m each minute.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
