Charlie created a scatter plot of the relationship between the time in minutes, y, it took him to solve a puzzle and the number of times he had solved the puzzle, x. He then drew the trend
line and calculated the equation to be y=-2.8x+45. What does the slope of the trend line
represent?

1. On average, Charlie solves the puzzle 2.8 minutes faster each time he solves it.

2.On average, Charlie solves the puzzle 2.8 minutes slower each time he solves it.

3.On average, it takes 45 fewer minutes to solve the puzzle each time Charlie solves it.

4.On average, it takes 45 more mitigate to solve the puzzle each time Charlie solves it.
