Tina recorded data to represent the amount of carbon dioxide in the atmosphere. She determined the
equation of the least squares line to be y = 357 +0.17%, where x is the number of months since
January 1995, and y is the number of carbon dioxide molecules per million air particles. What does the
value 357 represent in this context?

Respuesta :

Using linear function concepts, it is found that the value 357 represents the amount of carbon dioxide in the atmosphere in January 1995.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, the linear function for the amount of carbon dioxide in the atmosphere in x months after January 1995 is given by:

y = 357 + 0.17x.

The y-intercept is of 357, hence the value 357 represents the amount of carbon dioxide in the atmosphere in January 1995(which is the equivalent to month 0).
