Decide which graph shows a proportional relationship is it a DB or C
Without any specific information or context provided, it is not possible to determine which graph (DB or C) represents a proportional relationship.
In order to determine which graph shows a proportional relationship, it's important to understand what a proportional relationship means. In a proportional relationship, as one variable increases or decreases, the other variable also increases or decreases in a consistent manner.
Since you mentioned options "DB" and "C," I assume you have two graphs to compare. To make a decision, we need to analyze the graphs and look for a consistent pattern.
If "DB" and "C" are labels for the graphs, please provide a more specific description or an image of the graphs so that I can assist you further in determining which graph shows a proportional relationship.
To determine which graph shows a proportional relationship, we need to analyze the characteristics of the graphs and understand what proportional relationship means.
A proportional relationship is a type of relationship between two variables in which their ratio remains constant. In other words, as one variable increases or decreases, the other variable also increases or decreases by the same ratio.
Now, let's examine the two given options: DB and C.
To make an informed decision, we should carefully analyze the graphs and identify whether they exhibit a proportional relationship. Here are the steps you can follow to identify a proportional relationship in a graph:
1. Look at the slope: The slope represents the rate at which the graph is changing. In a proportional relationship, the slope remains constant throughout the entire graph. You can calculate the slope by selecting two points on the line and finding the ratio of the change in y-coordinates to the change in x-coordinates.
2. Check the origin: In a proportional relationship, the graph passes through the origin (0,0). This means that when both variables are zero, the proportion still holds.
3. Compare data points: Examine specific data points on the graph. If the ratio of the y-coordinate to the x-coordinate remains constant, then it indicates a proportional relationship.
Without the specific graphs provided, it is difficult for me to directly compare DB and C. However, you can apply the steps outlined above to each graph and determine whether they display a proportional relationship.
Remember, a proportional relationship can be visually identified by a straight line passing through the origin (0,0) with a constant slope throughout the graph.
