Answer 1

To determine the correct statement about the slope of the graph, the specific details of the graph (like the temperature values at certain time intervals) would need to be provided. Since I can't see the graph, I recommend you analyze the slope by identifying two points on the line—let's say point A at (x1, y1) and point B at (x2, y2).

You can calculate the slope (m) using the formula:

\[
m = \frac{y2 - y1}{x2 - x1}
\]

Where:
- \( y2 \) and \( y1 \) correspond to the temperature values,
- \( x2 \) and \( x1 \) correspond to the time values in minutes.

Once you calculate the slope, you can match it with one of the provided options (A, B, C, or D) to see which one accurately describes the increase in temperature per minute.

If you can provide more details about the graph (such as specific temperature values and their corresponding times), I can help you calculate the slope more accurately!
