Which do you think is the more informative and why?Linear relationships between two quantities can be described by an equation or a graph.

When linear relations are described as a graph the
intercepts of the graph can be easily identified. It is also easy to determine the
general slope of the graph, i.e. whether it is positive or negative. Though to determine
the exact slope of the graph, most often the equation is easier to work
with.

It is also easier to work with an equation as all the
information that a graph can provide is accessible without having to actually plot the
graph. That does take a little more time and effort.

The
choice between using the equation or the graph is more to do with what information needs
to be collected. It would difficult to say that one of them is better than the
other.
