The graph that represents direct variation is C.
How to determine the graph of direct variation.
The graph of direct variation is a straight line passing through the origin (0,0), demonstrating a constant ratio between variables.
Graph A has both x and y intercepts. It does not pass through the origin. It cannot be a direct variation graph.
Graph B is a curve representing constant change in the ratio of the dependent and independent variables.
Graph D is horizontal line which parallel to the horizontal axis. It does not represent a variation.
Graph C passes through the origin and with a slope which show direct proportionality between the variable.
