The slope of the regression line depicted on the scatter plot is the ratio of the rise to the run of the graph, hence, the slope is 3.
Given the coordinates of the scatter plot as follows :
(24, 127) and (36, 163)
The slope is defined as : [tex]\frac{Rise} {Run} [/tex]
Rise = y2 - y1 = 163 - 127 = 36
Run = x2 - x1 = 36 - 24 = 12
Slope = [tex]\frac{36} {12} = 3 [/tex]
Therefore, the slope of the trend line on the scatterplot attached is 3
