The equation of the linear regression line represents the relationship between the number of laps a person can swim, x, and the number of minutes a person can run, y. yˆ=52x+6 What does the slope of the line represent? For every 5 laps that a person can swim, the number of minutes they can run increases by 2. For every 2 laps that a person can swim, the number of minutes they can run increases by 5. For every 5 laps that a person can swim, the number of minutes they can run decreases by 2. For every 2 laps that a person can swim, the number of minutes they can run decreases by 5.
