Question

Which of the following is an appropriate line of best fit for the scatter plot showing the number of households, in millions, that have cable television over eight consecutive years?

1) y = -0.13x + 4.65
2) y = 0.13x + 4.65
3) y = -0.67x + 4.05
4) y = 0.67x + 4.05

Answer 1

The appropriate line of best fit for the scatter plot is y = -0.13x + 4.65, which represents the trend in the data points and allows for future predictions.

Step-by-step explanation:

The appropriate line of best fit for the scatter plot showing the number of households that have cable television over eight consecutive years is y = -0.13x + 4.65.

The line of best fit represents the trend in the data points and allows us to predict the number of households with cable television for future years.

For example, if x represents the number of years since the start of the data collection, and y represents the number of households with cable television, we can use the equation y = -0.13x + 4.65 to estimate the number of households for any given year.
