Question

football practices
the equation for the line of best fit is $y = 0.3x - 1.3$. according to the equation, which of these statements is true?
during a 115 - minute practice, vincent would likely drink about 33 fluid ounces of water.
during a 90 - minute practice, vincent would likely drink about 31 fluid ounces of water.

Explanation:

Step1: Substitute \(x = 115\) into \(y = 0.3x-1.3\)

\(y=0.3\times115 - 1.3\)
\(y = 34.5-1.3\)
\(y=33.2\approx33\)

Step2: Substitute \(x = 90\) into \(y = 0.3x - 1.3\)

\(y=0.3\times90-1.3\)
\(y = 27-1.3\)
\(y = 25.7
eq31\)

Answer:

During a 115 - minute practice, Vincent would likely drink about 33 fluid ounces of water.
