The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.

If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
A relationship that occurs when variable quantities are directly proportional to one another. A linear relationship can be represented on a graph as a STRAIGHT LINE. Linear relationships always follow the formula: y=mx+b where y is the value of the y-coordinate, where my is the slope of the line, where x is the value of the x-coordinate, and b is the y-intercept
You cannot represent a proportional relationship using an equation.
In math, proportional means that two quantities always have the same relative size. For example, the lengths of these two shapes are proportional (one shape's length is always twice as large as the other.)
If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
