An input in a graph typically represents the independent variable, often plotted along the x-axis. The proportion reflects the relationship between the input and the dependent variable (plotted on the y-axis), showing how changes in the input affect the output. For linear relationships, the proportion is constant, indicating that equal changes in the input result in equal changes in the output. In non-linear relationships, the proportion may vary, illustrating more complex interactions between the two variables.
A graph represents a function if and only if every input generates a single output.
Usually x (independent) variable is the input and y (dependent variable) is the output.
When the data on the graph is continuous,it does make sense to connect the points on the graph of 2 related variables.
Go to the Wolfram Alpha site and type the following in the input box: |x|

When quantities are related this way we say that they are in direct proportion.
a circle graph. is the answer
The graph of the function y(x) = 1/x is a hyperbola.
If it is a straight line through the origin then it represents a direct proportion.
A kind of weird line that is straight.

straight line
Assuming both the scales on the graph are linear (that is to say that the numbers go up evenly) then YES, a graph which shows direct proportion must be a straight line. It must also pass through the origin (0,0). A straight line which does not pass through the origin is NOT showing direct proportion. Duncan
