The weight of a cheetah can be based on the number of miles they run a day. The line of best fit for this dataset is y=195−7.3x
. The table represents the scatter plot of data. Find the weight of a cheetah that runs 7 miles, and state whether extrapolation or interpolation is occurring.

Answer 1

To find the weight of a cheetah that runs 7 miles using the line of best fit \( y = 195 - 7.3x \), we substitute \( x = 7 \) into the equation:

\[ y = 195 - 7.3(7) \] \[ y = 195 - 51.1 \] \[ y = 143.9 \]

The estimated weight of a cheetah that runs 7 miles is 143.9 pounds.

Since 7 miles is outside the range of miles (0 to 10) that were provided in the dataset, this would be considered extrapolation.

Thus, the correct answer is:

143.9 pounds and extrapolation.
