How does an inverse variation graph differ from a direct variation graph?
An inverse variation graph shows a hyperbolic relationship between two variables, where as one variable increases, the other decreases. This is represented by a curved line that approaches the x and y axes but never touches them.
A direct variation graph, on the other hand, shows a linear relationship between two variables, where as one variable increases, the other also increases or decreases in a consistent proportion. This is represented by a straight line that passes through the origin.
In summary, the main difference is the shape of the line on the graph - a curved line for inverse variation and a straight line passing through the origin for direct variation.
