The scatterplot below shows the amount of electric energy generated, in millions of megawatt-hours, by nuclear sources over a10‑year period. Of the following equations, which best models the data in the scatterplot?

A scatterplot with a linear model is shown.Which best describes the linear model? A. The linear model does not describe the data well because there are not the same amount of points above the line as below the line. B. The linear model describes the data well because the points are scattered above and below the line. C. The linear model does not describe the data well because it does not go through any of the points. D. The linear model describes the data well because some of the points are close to the line.

Which of the following parameters can be used to enlarge or reduce the size of data points in a scatter plot?

Three scatter plots are shown below. Use them to answer the questions below the graphs.A. For one of the three scatter plots, r = –0.83. Which one do you think it is?Explain.B. Which graph has a least-squares fit line with the equation y = 0.6x + 1.75?Explain.

The scatterplot shows the number of housing units in 2010 and 2018 for each of 11 US states. A line of best fit with equation y=ax, where a is a constant, is also shown. A point lies above this line if and only if it represents a state with an increase in housing units from 2010 to 2018 greater than 7%. What is the value of a?
