To determine the constant of proportionality (unit rate) from a graph, you typically look at the rise over run (change in y over change in x) between two points on the line.
Without the visual of the graph, I can't provide the exact answer. However, I can guide you on how to find the constant of proportionality:
- Identify two points on the line, (x1, y1) and (x2, y2).
- Calculate the change in y (Δy = y2 - y1) and the change in x (Δx = x2 - x1).
- The constant of proportionality is found by dividing the change in y by the change in x: k = Δy / Δx.
Once you have your k value, you can match it with the answer choices you've provided:
- \( \frac{3}{1} \) which is 3,
- \( \frac{1}{3} \),
- 3,
-
If you can provide the coordinates of two points from the graph, I can help you calculate the constant of proportionality directly!
