The graph of a linear equation contains the points (4,1) and (-2,-11). which. also lies on the graph (1, 1) (1,-5) (1,-2) (1,-7)

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.
