The constant of proportionality can be found by examining the ratio of the y-coordinates to the corresponding x-coordinates.
Between the points (0,0) and (2,3), the ratio of the y-coordinate to the x-coordinate is 3/2.
Similarly, between the points (2,3) and (4,6), the ratio of the y-coordinate to the x-coordinate is also 3/2.
Therefore, the constant of proportionality is 3/2.
Use the image to answer the question.
A graph with x-axis and y-axis ranging from 0 to 8 in unit increments shows a line. The line passes through the following plotted points: left parenthesis 0 comma 0 right parenthesis; left parenthesis 2 comma 3 right parenthesis; and left parenthesis 4 comma 6 right parenthesis.
Identify the constant of proportionality from the graph.
