A data set shows the number of practice throws players in a basketball competition made and the number of free throws they made in a timed competition.
Practice throws  4  10  6  15  0  7  11 

Free throws  8  23  9  34  5  11  27 
Use technology to find the equation and coefficient of determination for each type of regression model. Use the number of practice throws for the input variable and the number of free throws for the output variable. Round all decimal values to three places.
