Depending on whether you are solving a unit rate from a graph or without a graph, you can the unit rate by dividing the y coordinates by the x coordinates. If you are looking for a simpler answer, then you simply divide whatever independant value by its dependent counterpart. For example, if you are looking for the price per object, then you would divide the price by the object! Lets say for a bundle of 10 toilet rolls it costs $11.55. You would divide 11.55/10 and get a unit price of $1.15 cents rounded to the hundredth decimal. I hope this helps! :)
