Trial 1 tread line: y = 5.0242x – 56.376

                                   R2 = 0.6008

Trial 2 tread line: y = 5.8242x – 47.776

                                      R2 = 0.821

Trial 3 tread line: y = 6.1091x – 65.291

                                       R2 = 0.723

Given the general line of the equation y = mx + b, the inverse of the slope is 1/m. Determine the inverse of the slope (the reaction rate) for each of your trend lines.

Explanation / Answer

Trial 1 tread line:

y = 5.0242x – 56.376 = mx + b

m = 5.0242 ; 1/m = 0.199

Trial 2 tread line:

y = 5.8242x – 47.776 = mx+b

m = 5.8242 ; 1/m = 0.1717

Trial 3 tread line:

y = 6.1091x – 65.291 = mx + b

m = 6.1091 ; 1/m = 0.1637
