of the camera she adds.
this situation can be modeled as a linear relationship.
complete the statement that describes the situation.
the drones battery will last minutes if no weight is added. the battery life will
decrease by of weight added.

Explanation:

Step1: Find battery life at 0 weight

When \( x = 0 \) (no weight added), from the graph, the \( y \)-intercept (battery life) is 16 minutes.

Step2: Calculate slope (rate of decrease)

Take two points: \((0, 16)\) and \((100, 13)\) (approximate from graph). Slope \( m=\frac{y_2 - y_1}{x_2 - x_1}=\frac{13 - 16}{100 - 0}=\frac{- 3}{100}=-0.03\). The negative sign indicates decrease. So for every 1 gram added, battery life decreases by \( \frac{3}{100} = 0.03 \) minutes? Wait, no, let's check another way. Wait, from \( x = 0 \) (16 min) to \( x = 100 \), \( y \) goes from 16 to 13, so change in \( y \) is \( 13 - 16=-3 \), change in \( x \) is 100. So the rate is \( \frac{-3}{100} \) minutes per gram, meaning for each gram added, battery life decreases by \( \frac{3}{100}=0.03 \) minutes? Wait, but maybe better to see the first part: when no weight (\( x = 0 \)), battery life is 16 minutes. Then, to find the decrease per gram, let's take two points: (0,16) and (100,13). The slope is \( \frac{13 - 16}{100 - 0}=\frac{-3}{100}=-0.03 \), so the battery life decreases by 0.03 minutes per gram, or equivalently, 1 minute per \( \frac{1}{0.03}\approx33.33 \) grams? Wait, maybe the problem expects the first blank as 16, and the second part: let's see, from x=0 (16) to x=100 (13), the decrease is 3 minutes over 100 grams, so per gram, decrease is \( \frac{3}{100}=0.03 \) minutes, or per 100 grams, decrease by 3 minutes. Wait, the problem says "decrease by [ ] of weight added". Wait, maybe the first blank is 16, and the second: let's check the graph again. At x=0, y=16. At x=100, y=13. So the change in y is 16 - 13 = 3 minutes over 100 grams. So the rate of decrease is \( \frac{3}{100}=0.03 \) minutes per gram, or 1 minute per \( \frac{100}{3}\approx33.33 \) grams. But maybe the problem wants the first blank as 16, and the second: let's see, the first part: when no weight (x=0), battery life is 16 minutes. Then, the battery life decreases by 1 minute for every \( \frac{100}{3}\approx33.33 \) grams? Wait, no, maybe the problem has a typo, but from the graph, the y-intercept is 16, so first blank is 16. Then, to find the decrease per gram, slope is \( \frac{13 - 16}{100 - 0}=-0.03 \), so for each gram added, battery life decreases by 0.03 minutes. But maybe the problem wants "1 minute for every \( \frac{100}{3} \) grams" or "3 minutes for every 100 grams". Let's check: from x=0 (16) to x=100 (13), 100 grams added, battery life decreases by 3 minutes. So per 100 grams, decrease by 3 minutes, or per gram, decrease by \( \frac{3}{100}=0.03 \) minutes. But the first blank is 16.

Answer:

The drone's battery will last \(\boldsymbol{16}\) minutes if no weight is added. The battery life will decrease by \(\boldsymbol{1}\) minute for every \(\boldsymbol{\frac{100}{3} \approx 33.33}\) grams (or 3 minutes for every 100 grams, or 0.03 minutes per gram) of weight added. (But based on the graph's y - intercept, first blank is 16. For the second, using two points (0,16) and (100,13), the decrease in battery life over 100 grams is 3 minutes, so per gram, \( \frac{3}{100}=0.03 \) minutes decrease, or 1 minute decrease per \( \frac{100}{3}\) grams. However, the most straightforward from the y - intercept is 16 for the first blank.)

(Note: If we consider the first part, when \( x = 0 \), \( y = 16 \), so first blank is 16. For the second, let's recalculate slope properly. Let's take (0,16) and (60,14.5) maybe? Wait, no, the graph shows at x=0, y=16; at x=100, y=13. So slope \( m=\frac{13 - 16}{100 - 0}=-\frac{3}{100}=-0.03 \). So the battery life decreases by 0.03 minutes per gram, or 1 minute for every \( \frac{1}{0.03}\approx33.33 \) grams. But the problem says "decrease by [ ] of weight added" – maybe the first blank is 16, and the second: from the graph, when no weight, 16 minutes. The rate of decrease is 3 minutes per 100 grams, so 1 minute per \( \frac{100}{3}\) grams, or 0.03 minutes per gram. But the first blank is definitely 16.)

Final answers: First blank: 16; Second blank: 1 minute for every \( \frac{100}{3} \) grams (or 0.03 minutes per gram, or 3 minutes per 100 grams). But based on the graph's y - intercept, first is 16.
