What are the solutions to the following system? -2x +y=-5
y=-3x2 +5
O (0, 2)
O (1,-2)
(12.-1) and (- 13.-1)
(15.-10) and (- 15.-10

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.
