Answer

The provided statement does not make sense.

Work Step by Step

Variation formulas are the formulas that define the relation between two quantities such that if one quantity varies how does it affect another quantity. In direct variation, one variable varies directly at a time as soon as another variable varies. Thus if one quantity increases in a system another quantity also gets increased. Direct variation can be defined as: $y=kx$ Here, quantity y varies directly as soon as x varies, and k is known to be a constant of variation. Thus, the graph of the direct variation equation also shows the same variation, i.e., if one quantity, x increases in the graph then another quantity, y will also increase in that graph.
