Question

audreys swimmers
the equation for the line of best fit is ( y = -2x + 49 ). according to the equation, which of these statements is true?
a swimmer who just joined the team would likely have a best time of about 49 seconds.
a swimmer who has been on the team for 2 years would likely have a best time of about 49 seconds.

Explanation:

Step1: Substitute \(x = 0\) (new - joiner) into the equation \(y=-2x + 49\)

When \(x = 0\), \(y=-2\times0+49=49\)

Step2: Substitute \(x = 2\) (2 - year member) into the equation \(y=-2x + 49\)

When \(x = 2\), \(y=-2\times2+49=-4 + 49=45
eq49\)

Answer:

A swimmer who just joined the team would likely have a best time of about 49 seconds.
