The equation of the linear regression line represents the relationship between the number of minutes a person can run, x, and the number of laps a person can swim, y. yˆ=2/5x+4 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 decreases 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 increases by 5.
The options are quite confusing because it's slightly implying a reverse of the true correlation. However, I'd go for B. Just plug in each of the values and observe the effect. A, C, and D are wrong.
