Answer:
A Demand Schedule is a table listing quantities demanded of a good at different prices
For Example;
Price ($) | Quantity Demanded (Units)
1 10
2 9
3 8
4 7
etc.
A Demand Curve displays the information from a Demand Schedule.
The Price is on the Y-axis, and the Quantity Demanded is on the X-axis, you just plot the points given , i.e. (10,1) , (9,2)
In reality the Demand Curve is an actual curve, but for basic examples the "Curve" is a straight downward sloping line from left to right, for the above example.
