In order to identify the constant of proportionality for this graph, we need to calculate the slope of the line. The slope represents the rate at which one variable (y-axis) changes with respect to the other variable (x-axis).
If we choose any two points on the line, we can calculate the slope using the formula:
Slope = (change in y) / (change in x)
Let's choose two points: (2, 6) and (4, 12).
change in y = 12 - 6 = 6
change in x = 4 - 2 = 2
Slope = 6 / 2 = 3
Therefore, the constant of proportionality for this graph is 3.
Using the points shown in the graph, identify the constant of proportionality for this graph
