To accurately answer your question regarding the graph, I would need to see the specific graph you are referring to. However, I can provide you with some general guidance on how to determine the y-intercept, the constant of proportionality, and the equation that represents a given graph.
-
Y-Intercept: This is the value of y when x is 0. In a graphical context, you can identify it as the point where the graph intersects the y-axis.
-
Constant of Proportionality: If a graph represents a proportional relationship (a straight line through the origin), the constant of proportionality is the ratio of y to x at any point on the line, which is the slope of the line.
-
Equation that Represents the Graph: The equation of a straight line can be written in the slope-intercept form, which is \( y = mx + b \), where \( m \) is the slope (constant of proportionality) and \( b \) is the y-intercept.
If you can provide more specific details about the graph (like key points or shapes), I can assist further with matching the responses to the inputs you mentioned.
