Question

A computer downloads a
-minute video at a constant rate. What does the slope represent?


A graph has time (seconds) on the x-axis, and download (megabytes) on the y-axis. A line goes through (0, 0) and (15, 300).
Clear Check

Unit rate of megabytes per download



Unit rate of seconds per megabyte



Downloading speed in megabytes per second



Number of seconds remaining for download to complete

Answer 1

In the context of the graph you provided, which has time (in seconds) on the x-axis and download size (in megabytes) on the y-axis, the slope of the line represents the downloading speed.

To break down the options:

- **Unit rate of megabytes per download**: This doesn't apply, as the graph does not measure "downloads" but rather the amount of data downloaded over time.

- **Unit rate of seconds per megabyte**: This is the inverse of the slope, so it doesn't accurately describe what the slope represents.

- **Downloading speed in megabytes per second**: This is correct. The slope is given by the formula (change in y) / (change in x), which corresponds to the number of megabytes downloaded per second.

- **Number of seconds remaining for download to complete**: This does not apply as the slope does not indicate time remaining but rather the rate of download.

Thus, the correct answer is:

**Downloading speed in megabytes per second**.
