The scale on a map shows that 10 kilometers is represented by 4 centimeters. Which proportion can be used to find the actual distance, x, represented by 20 centimeters on the map? StartFraction 10 over 4 EndFraction = StartFraction x over 20 EndFraction
StartFraction 10 over 4 EndFraction = StartFraction 20 over x EndFraction
StartFraction 10 over 20 EndFraction = StartFraction 4 over x EndFraction
StartFraction 10 over 20 EndFraction = StartFraction x over 4 EndFraction

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
