No.A directly proportional graph has an equation of the form y = mx. It always passes through the origin.A linear graph will have an equation in the from y = mx + c. This has a y-intercept at (0, c). It doesn't pass through the origin unless c = 0. The directly proportional graph is a special case of a linear graph.

If two quantities are proportional, then they have a constant ratio.If the ratio is not constant, the two quantities are said to be non-proportional.Proportional will always go through the origin on a graph. (0,0)Graph will always be a straight line.Non-proportional line does not go through the origin.

The x value and the y value are directly and invertly related on a graph. This only occurs in a specific type of graph called a proportional graph.

It makes a line ,it goes through the origin, it has a constant

1. You can tell the difference because the proportional one has the same slope while the inversely one has opposite reciprocal slope.

It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.

If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.

The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.

It is true in the case of inversely proportional relationship.
