2. Use the graph the answer the following questions. (3 points) a. The constant of proportionality is . b. Write an equation that represents this graph . c. This is a proportional relationship because the y-intercept is .

It seems that you are referring to a graph that isn't visible in this format. However, I can guide you on how to answer those questions if you provide the necessary details from the graph.

Here’s how to approach each question:

a. **Constant of Proportionality**: This is often represented by the variable \( k \) in the equation \( y = kx \). To find it, look at the ratio of \( y \) to \( x \) for a few points on the graph. If you have a point (x, y), the constant of proportionality can be calculated as \( k = \frac{y}{x} \).

b. **Equation that Represents the Graph**: Once you have determined the constant of proportionality \( k \), you can write the equation in the form \( y = kx \).

c. **Proportional Relationship**: A relationship is considered proportional if it goes through the origin (0, 0) and is represented as a straight line. Thus, if the line intersects the y-axis at the origin, you would state that "the y-intercept is 0".

Please provide more specific details from the graph, such as coordinates of points or the slope of the line, in order for me to assist you further!
