To answer these questions accurately, I would need to see the graph youโre referring to. However, I can provide you with some general guidelines and insights based on typical characteristics of proportional relationships:
### a. The constant of proportionality is:
In a proportional relationship, the constant of proportionality (k) can be found by determining the ratio of y to x (y/x) for any point other than the origin. If you're indicating that the constant is 0, it suggests that there is no change in y for any change in x, meaning the line may be horizontal (y = 0).
### b. Write an equation that represents this graph:
If the constant of proportionality is 0, the equation representing the graph is typically:
\[ y = 0 \]
This indicates that no matter the value of x, y remains constant at 0.
### c. This is a proportional relationship because the y-intercept is:
In a proportional relationship, the y-intercept must be 0, which means the graph goes through the origin (0,0). Given the constant of proportionality is 0, the statement would conclude with:
"The y-intercept is 0."
If you have specific details from the graph or if you can describe it, I could provide a more tailored response!
