What is a proportional relationship graph?

A proportional relationship graph is a type of graph that represents a relationship between two variables that are directly proportional to each other. In other words, as one variable increases, the other variable also increases at a constant rate.

When plotting a proportional relationship on a graph, the resulting graph will be a straight line that passes through the origin (0,0). This indicates that when one variable is zero, the other variable is also zero.

Proportional relationship graphs can be used to visualize and analyze relationships between two variables, such as distance and time, cost and quantity, or speed and time. By analyzing these graphs, one can determine the rate at which one variable changes in relation to the other variable.

Overall, proportional relationship graphs provide valuable insight into the relationship between two variables and can help in decision-making, problem-solving, and understanding patterns and trends in data.
