Agraph is drawn (see picture). explain how you know that y is not directly proportional to x.

A graph that represents a proportional relationship between y and x will have a straight line that passes through the point of origin (0, 0). The graph shown therefore doesn't represent a graph where y is directly proportional to x.

For a graph representing a relationship where y is directly proportional to x, (y = kx), the line of the graph passes through the point of origin (0, 0).

When y is directly proportional to x, the quantity of y changes along with the quantity of x.

The graph shown has a line that doesn't pass through the point of origin (0, 0), so it is not a proportional graph and does not represent a relationship where y is directly proportional to x.

See the image attached showing a proportional graph.

Therefore, a graph that represents a proportional relationship between y and x will have a straight line that passes through the point of origin (0, 0). The graph shown therefore doesn't represent a graph where y is directly proportional to x.
