If it is a straight line through the origin then it represents a direct proportion.
straight line
If the variables x and y are in direct proportion then the graph of y against x is a straight line through the origin. If the variables x and y are in inverse proportion then the graph of y against x is a rectangular hyperbola. Alternatively, the graph of y against 1/x (or 1/y against x) is a straight line through the origin.
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
Unless it is a direct proportion, the straight line does not have to start from zero.
