The temperature of assistance was recorded over several minutes as shown in the graph below the graph displays a linear relationship between the temperature measured in degrees Celsius, and the number of minutes the substance was being observed, which statement best describes a slope of the graph. The temperature is increasing 3.25°C each minute the temperature is increasing 5.25°C eight minute the temperature is increasing 1.25 Celsius eight minute the temperature is increasing 7.25 Celsius eight minute
The statement that best describes the slope of the graph is "The temperature is increasing 3.25°C each minute."
To determine the slope of the graph, we can examine the change in temperature (in degrees Celsius) divided by the change in time (in minutes). Let's evaluate the given options:
Option 1: The temperature is increasing 3.25°C each minute.
Option 2: The temperature is increasing 5.25°C eight minutes.
Option 3: The temperature is increasing 1.25°C eight minutes.
Option 4: The temperature is increasing 7.25°C eight minutes.
To calculate the slope, we need to find the change in temperature and divide it by the change in time:
Slope = Change in temperature / Change in time
For option 1, the change in temperature is 3.25°C, and the change in time is 1 minute. So the slope is:
Slope = 3.25°C / 1 minute = 3.25°C/minute
For option 2, the change in temperature is 5.25°C, and the change in time is 8 minutes. So the slope is:
Slope = 5.25°C / 8 minutes = 0.65625°C/minute
For option 3, the change in temperature is 1.25°C, and the change in time is 8 minutes. So the slope is:
Slope = 1.25°C / 8 minutes = 0.15625°C/minute
For option 4, the change in temperature is 7.25°C, and the change in time is 8 minutes. So the slope is:
Slope = 7.25°C / 8 minutes = 0.90625°C/minute
Therefore, the statement that best describes the slope of the graph is: "The temperature is increasing 3.25°C each minute."
