To determine the constant of proportionality from a graph, you'll typically look for a set of points that show a linear relationship passing through the origin (0,0).
The constant of proportionality (often denoted as \( k \)) is found by applying the formula:
\[ k = \frac{y}{x} \]
for the points on the line.
- Identify a point (x, y) on the graph.
- Substitute the x and y values into the formula to find \( k \).
For example, if you have the point (2, 4), then:
\[ k = \frac{4}{2} = 2 \]
Please provide the specific points or values from the graph to calculate the constant of proportionality accurately.
