A French car company wants to cut costs by using cheaper low-carbon steel in its car frames. To determine how varying the carbon content will affect strength, company engineers manufactured several car frames. 

 

For each car frame, the engineers noted the percentage of carbon, \( x \) , as well as the weight it could support (in kilograms), \( y \) . 

 

The correct least squares regression line for the data set is: 

\( y = 282.792 x + 838.003 \) 

 

Use it to complete the following sentence:

 

 If a car frame has one additional percentage point of carbon, the least squares regression line predicts it can support ____more kilograms. 

Answer

1123.623
