Find a vector equation and parametric equations for the line. (Use the parameter t.) The line through the point (0, 11, −7) and parallel to the line x = −1 + 3t, y = 6 − 2t, z = 3 + 6t r(t) = ⟨3t, 11−2t, −7+6t⟩ (x(t), y(t), z(t)) = 3t, 11−2t, −7+6t

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.
