A surf instructor has an initial fee of $12 and charges $8 per hour for lessons. Write a linear equation that represents the total cost of surf lessons after a certain number of hours. 1.y-intercept = (0, 12), point = (x, y) 2.m = 8 3. 8 = y − 12 x − 0 → 8 = y − 12 x 4.Solve for y:

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.
