State whether the relationship between x and y in y = 2x - 3 is proportional or non-proportional. explain.

They would be proportional when y= kx, k is a constant, so, y=2x - 3 is non- proportional. In mathematics, two variables are proportional if a change in one is always goes with a change in the other. They are prop. If one variable is always the product of the other and a constant, but in the equation above the y is not just a product of the x and a constant (2). It's a product of the x and a constant 2 minus 3.

Good luck :)

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.
