Which table of ordered pairs represents a proportional relationship?

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
