Interpreting Slope and y-Intercept in Equations

What does the equation y = 7.5x + 40 represent in the context of Colton's experiment?

• The relationship between the temperature and the boiling point of water.

• The relationship between the volume of water and its temperature.

• The relationship between the number of minutes and the temperature of the water.

• The relationship between the number of minutes and the volume of water.

What does the coefficient 7.5 in the equation y = 7.5x + 40 represent?

• The initial temperature of the water.

• The rate at which the temperature of the water increases per minute.

• The boiling point of the water.

• The total time taken to heat the water.

In the equation y = 7.5x + 40, what does the value 40 represent?

• The rate of temperature increase per minute.

• The boiling point of the water.

• The initial temperature of the water.

• The total time taken to heat the water.

What is the temperature of Colton's pot of water after 16 minutes?

• 120 degrees Fahrenheit

• 140 degrees Fahrenheit

• 160 degrees Fahrenheit

• 180 degrees Fahrenheit

How do you calculate the temperature of the water after a certain number of minutes using the equation y = 7.5x + 40?

• Divide the number of minutes by 7.5 and add 40.

• Subtract 40 from the number of minutes and multiply by 7.5.

• Multiply the number of minutes by 7.5 and add 40.

• Multiply the number of minutes by 40 and add 7.5.

What is the boiling point of water in degrees Fahrenheit?

• 200 degrees Fahrenheit

• 160 degrees Fahrenheit

• 212 degrees Fahrenheit

• 100 degrees Fahrenheit

After 16 minutes, the temperature of the water is 160 degrees Fahrenheit. How much additional time is needed for the water to reach 212 degrees Fahrenheit?

• 5 minutes

• 7 minutes

• 9 minutes

• 11 minutes

What is the first step to find the additional time needed for the water to boil after 16 minutes?

• Subtract 40 from 212.

• Add 40 to 212.

• Divide 212 by 7.5.

• Multiply 212 by 7.5.

What is the result of dividing 172 by 7.5?
