The linear relationship shows a proportional relationship because the graph passes through the point (0, 0).
A proportional relationship is a special kind of linear relationship where the ratio of the two variables is constant.
A proportional relationship can be represented by a line that passes through the origin (0, 0), meaning that when one variable is zero, the other variable is also zero.
In this graph, the ratio of the number of apples to the time is 50/1, which is constant. The line passes through the origin, so it shows a proportional relationship.
The graph of the number of apples against time exhibits a proportional relationship, as indicated by the line passing through the origin and the constant ratio between the variables. This type of relationship is common in various real-world scenarios, such as constant speed, uniform motion, or direct proportionality between quantities.
