Understanding Temperature Graphs

The video tutorial explains how to interpret a graph of temperature in New York City, measured in degrees Celsius, as a function of time in hours after midnight. It covers understanding time conversion from hours after midnight to standard time, identifying the y-intercept, and analyzing positive, negative, increasing, and decreasing intervals on the graph. The tutorial emphasizes matching statements with graph features to understand temperature changes throughout the day.

What does T of T represent in the context of the video?

• The time in hours after noon

• The temperature in New York City in degrees Celsius

• The speed of wind in New York City

• The humidity level in New York City

If it is 14 hours after midnight, what time is it?

• 2 a.m.

• 4 a.m.

• 2 p.m.

• 4 p.m.

What does the y-intercept of the graph indicate?

• The temperature at noon

• The average temperature of the day

• The temperature at the beginning of the day

• The highest temperature of the day

What is the significance of the temperature being negative at the y-intercept?

• It signifies the average temperature of the day

• It represents the temperature at the beginning of the day

• It shows the temperature at the end of the day

• It indicates the temperature at noon

What does it mean when the graph is above zero?

• The temperature is decreasing

• The temperature is constant

• The temperature is below freezing

• The temperature is above zero

During which time period was the temperature above zero?

• Between 2 a.m. and 2 p.m.

• Between 8 a.m. and 8 p.m.

• Between 6 a.m. and 6 p.m.

• Between 10 a.m. and 10 p.m.

What analogy is used to explain increasing and decreasing intervals?

• A pendulum

• A thermometer

• A clock

• A roller coaster

What does an increasing interval on the graph signify?

• The temperature is fluctuating

• The temperature is increasing

• The temperature is constant

• The temperature is decreasing

What time does the temperature start increasing according to the video?

• 8 a.m.

• 6 a.m.

• 4 a.m.

• 2 a.m.

What does a decreasing interval on the graph indicate?

• The temperature is fluctuating

• The temperature is constant

• The temperature is decreasing

• The temperature is increasing
