To find the slope of the graph you pick any piece of the line, and divide the vertical difference between its ends by the horizontal difference between its ends. If the graph is distance versus time then the slope represents the speed.
Range is all real
(-inf, inf )
Product A= 8oz = 1.36 x 2= 2.72. 16oz = 2.72
product B= 16oz= 3.20
so Product A has the lower unit price.
