To find the weight of a cheetah that runs 7 miles using the line of best fit equation \( y = 195 - 7.3x \), we substitute \( x = 7 \) into the equation:
\[ y = 195 - 7.3(7) \]
Calculating this:
\[ y = 195 - 51.1 \] \[ y = 143.9 \]
Thus, the weight of a cheetah that runs 7 miles is 143.9 pounds.
Since 7 miles is outside the range of the data provided in the table (which only goes up to 10 miles), this is considered extrapolation.
Therefore, the correct response is:
143.9 pounds and extrapolation.
