Answer:

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ΕΎ is equal to k, where k is the unit rate. The point (1, k) is a point on the graph. Hope that was helpful in some way.

Answer:

The graph of a proportional relationship is a straight line that passes through the origin. Proportional quantities can be described by the equation y = kx, where k is a constant ratio. You can tell that the relationship is directly proportional by looking at the graph. The graph is a straight line and it passes through the origin.
