WebThe graph of a direct variation, which is a PROPORTIONAL LINEAR RELATIONSHIP, is a line that passes through the origin [that is, it must pass through the 0, 0 coordinate on the graph. NOTE: If the line of the graph does NOT pass through the origin [0, 0 coordinate on the graph] then the graph CANNOT be a proportional linear relationship. Copy and … WebApr 7, 2024 · For a direct variation, y = mx, therefore, the graph of a direct variation is a straight line passing through the origin. For an inverse variation, y = k/x where, x ≠ 0, k ≠ 0 Therefore, the graph of an inverse variation is neither a straight line nor does it pass through the origin as x can never be 0.
