Question

- Scientists are preparing two satellites to be launched. The equation y 6400x represents the number of miles, y, that the satellite, Space Explorer B, flies in a hours. The graph below represents the number of miles, y, that the satellite, Space Explorer A, flies in x hours.​

Answer 1

Explanation:

From the graph A find slope = (32000-16000)/(10/5)=3200

So for the equation y=3200x plug 1 in you get 3200

For B if you plug in 1 you get 6400 miles per hour

6400-3200=3200

A travels 3200 miles per hour slower than B

Answer 2

Answer: 3200, less

Explanation:

The rate at which the space explorers fly in miles per hour is the slope.

Space explorer B flies at a rate of 6400 miles per hour. This is because

y=mx+b, where m is the slope.

Space explorer A flies at a rate of (32000-16000)/(10-5) = 3200 miles per hour. Slope is (y2 - y1) / (x2 - x1) where the coordinates are (x1,y1) and (x2,y2).

Space explorer B - Space Explorer A = 6400 - 3200 = 3200.

Therefore space explorer A travels 3200 miles per hour less than explorer B.
