The graph shows the data points in the table and the exponential regression model associated with the data. A 2-column table with 5 rows. The first column is labeled days after treatment with entries 2, 4, 6, 8, 10. The second column is labeled number of weeds with entries 100, 26, 6, 2, 1. A graph shows days after treatment labeled 1 to 11 on the horizontal axis and number of weeds on the vertical axis. A line shows a downward trend. Based on the graph of the regression model, which is true? The number of weeds is decreasing by a multiplicative rate. The number of weeds is increasing by a multiplicative rate. The number of weeds is decreasing by an additive rate. The number of weeds is increasing by an additive rate.

The number of weeds is decreasing by an additive rate.

" Additive rate means there is change in the input and output values of any given data."

" A regression model helps us to know the relation between dependent variable and independent variable."

According to the question,

When the number of days increases there is a decrease in number of weeds. As a line shows downward trend.

Hence the number of weeds is decreasing by an additive rate.
