Challenge

Let's do one more task as practice!

Tehtävä

Swipe to start coding

You have the dataset about Abbisian cats where the number of calories the cat eats every day of a certain weight is indicated (array x - weight, y - number of calories).

[Line #19] Find the correlation coefficient between x and y (in any convenient way), the slope, and the intercept of a straight line which shows the trend.
[Lines #22-24] Print these values in the order mentioned above.
[Line #27] Build line using function line() and save in built_line variable using list(map()).
[Lines #30-31] Build the line using matplotlib.pyplot functions.
