Import the csv into your notebook. Use the data in the relevant columns to determine how age affects insurance costs:

$1.$ Plot a scatter plot with age on the x$-$axis and charges on the y$-$axis.

$2.$ Using linear$\_$model.LinearRegression$()$ from sklearn, fit a model to your data, and make predictions on data.

$3.$ Plot another scatter plot with the best$-$fit line.
