Which of the following is an INCORRECT interpretation or analysis of the graph shown? Note: the slopes were calculated based on the trendline through the data points shown. Only 4 data points were included in the slope for the 30 cm data.
The rate of PET is greatest at the largest light intensity and lowest at the smallest light intensity.
An ~ 2.6-fold difference in light intensity leads to an ~ 3.1-fold increase in PET activity.
The PET reaction at a light intensity of 570 lux is complete prior to the 14 minute time point.
The slope equations for each of the data sets is a good linear representation of the data.
The slopes are negative for each data set because the concentration of oxidized DCPIP is decreasing with time.

please answer correctly
PET reaction of a chloroplast suspension cocktail at different light intensities with a 10W LED bulb. The slope equations are: y=−9.46x+76.2,R2=0.99 for 1460 lux, y=−3.06+79.4,R2=0.99 for 570 lux, and y= −1.15+83.01,R2=0.97 for 305 lux. Q2. Which of the following is an INCORRECT interpretation or analysis of the graph shown? Note: the slopes were calculated based on the trendline through the data points shown. Only 4 data points were included in the slope for the 30 cm data. The rate of PET is greatest at the largest light intensity and lowest at the smallest light intensity. An ∼2.6-fold difference in light intensity leads to an ∼3.1-fold increase in PET activity. The PET reaction at a light intensity of 570 lux is complete prior to the 14 minute time point. The slope equations for each of the data sets is a good linear representation of the data. The slopes are negative for each data set because the concentration of oxidized DCPIP is decreasing with time.
