To find the weight of a cheetah that runs 7 miles using the line of best fit \( y = 195 - 7.3x \), we can substitute \( x = 7 \) into the equation:
\[ y = 195 - 7.3(7) \]
Calculating this gives:
\[ y = 195 - 51.1 \] \[ y = 143.9 \]
Thus, the weight of a cheetah that runs 7 miles is 143.9 pounds.
Next, we need to determine whether this situation involves extrapolation or interpolation. Since the given data only includes miles run up to 5 and the prediction (7 miles) is outside this range, we are extrapolating.
The correct response is:
143.9 pounds and extrapolation.
