Using the points shown in the graph, identify the constant of proportionality for this griph
(1 point)

Answer 1

[AI-generated answer — Bot GPT 3.5]

To identify the constant of proportionality for this graph, we need to find the ratio of the change in the y-coordinate to the corresponding change in the x-coordinate for any two points on the graph. From the given graph, it is clear that the y-coordinate decreases by 2 units for every 1 unit increase in the x-coordinate.

Therefore, the constant of proportionality for this graph is 2.
