To identify the constant of proportionality from the given data points (2,3) and (4,6), we can calculate the ratio of the change in the y-values to the change in the x-values.
Change in y-values = 6 - 3 = 3
Change in x-values = 4 - 2 = 2
Ratio = change in y-values / change in x-values = 3 / 2 = 1.5
Therefore, the constant of proportionality is 1.5.
(2,3) (4,6)
