To find the weight of a cheetah that runs 7 miles using the line of best fit, we will substitute \( x = 7 \) into the equation \( y = 195 - 7.3x \).
Let's do the calculation:
\[ y = 195 - 7.3(7) \] \[ y = 195 - 51.1 \] \[ y = 143.9 \]
Therefore, the weight of a cheetah that runs 7 miles is 143.9 pounds.
Since 7 miles is outside the range of miles run given in the table (which goes up to 10 miles), this prediction is based on extrapolation, not interpolation.
The correct response is:
143.9 pounds and extrapolation.
