Help??? what us the exponent of x and y???

I’m pretty sure the slope would be 1 since the x and y values increase by 1

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.

Ithink it’s b, hope this .
