Proportional Relationship Graph. The graph shows the relationship between the weight of an object on the Moon and its weight on Earth. It is a straight line.
Graph the above relationship and check whether it is proportional. Two values have a proportional relationship if their ratio the fraction formed when one is divided by the other is always the same. A linear equation is an equation whose solutions are ordered pairs that form a line when graphed on a coordinate plane.
Write an equation for this relationship.
Graphs of Proportional Relationships The graph of a proportional relationship between two quantities is a straight line that starts at the origin 0 0. Figure PageIndex6 What is the constant of proportionality in this relationship. So Y the up and down part of the graph equals K The constant of proportionality you get it by dividing Y by X times X the side by side part of the graph This would equal YKX. When the graph of the linear relationship contains the origin the relationship is proportional.
