Graphing Trends and Predictions

The video tutorial explains the use of graphing to predict future trends. It demonstrates graphing time against height and hours against miles, showing how to plot data points and draw lines to observe trends and make predictions. The tutorial highlights the importance of setting up a clear grid and using expressions to calculate future values.

What is the primary purpose of using graphing in predictions?

• To confuse students

• To create colorful charts

• To predict future trends

• To replace mathematical calculations

In the time and height graph, what is the height at one day?

• Four

• Three

• Five

• Two

What is the height at three days in the graph?

• Four

• Seven

• Six

• Five

How does the rate of change appear from day one to day three?

• It decreases

• It becomes horizontal

• It remains constant

• It increases significantly

What does the graph suggest about the trend after day three?

• It will increase rapidly

• It will become more horizontal

• It will remain constant

• It will decrease

In the hours and miles graph, what does 'H' represent?

• Hours

• Height

• Hectares

• Horses

What does 'M' stand for in the hours and miles graph?

• Minutes

• Millimeters

• Miles

• Meters

At 1 hour, how many miles are covered according to the graph?

• Eight miles

• Six miles

• Four miles

• Two miles

What is the predicted distance at 5 hours?

• Twelve miles

• Ten miles

• Eight miles

• Fourteen miles

What is the mathematical expression derived from the hours and miles graph?

• Hours + 2 = Miles

• Hours - 2 = Miles

• Hours * 2 = Miles

• Hours / 2 = Miles
