<h3>Answer: Choice C</h3>

\text{Domain}: 0 \le x \le 55 and \text{Average rate of change over domain} = -1.45 (average rate of change is approximate)

=========================================================

The domain is the set of allowed x inputs of the function. The smallest x value shown is x = 0, which is from the point (0,80). The largest x value possible is x = 55 from the point (55,0)

The domain is the set of all values between 0 and 55, including both endpoints. Therefore, we get a domain of 0 \le x \le 55

Compute the slope of the line through (0,80) and (55,0) to find the average rate of change over the entire function domain.

m = (y2 - y1)/(x2 - x1)

m = (0 - 80)/(55 - 0)

m = -80/55

m = -1.45 approximately

The slope of the line through (0,80) and (55,0) is approximately -1.45, which is also the average rate of change over the entire domain.

Side note: the negative slope or negative rate of change indicates we are going downhill ultimately as we move from left to right.

What is the slope of line a?
marta [7]

Answer:

-1/3

Step-by-step explanation:

Slope is defined as "rise over run". If you count out the units, you should be able to see that your rise is 1 and your run is 3 and is pointing downward, so your answer is -1/3.

Alternatively you could use Slope Formula: m = \frac{y2-y1}{x2-x1}
