Final answer:
The correct graphical representation of the supply for records, according to the law of supply, is an upward-sloping line from left to right, known as a supply curve.
Step-by-step explanation:
Understanding the law of supply, we can deduce that the correct graphical representation of the supply for records must be a line that slopes upward from left to right. This graphical representation is known as a supply curve. The reason for this upward slope is because suppliers are typically willing to offer more for sale at higher prices, and less at lower prices. This relationship between price and quantity supplied is depicted on a graph where the price is indicated on the vertical axis (y-axis) and the quantity is on the horizontal axis (x-axis).
As you draw the graph, starting at the upper left, just as you would start writing, you label the vertical axis with price since 'p' comes before 'q' in the alphabet, and the horizontal axis with quantity. The curve that represents the supply will be upward sloping, which aligns with the mnemonic that both 'supply' and 'up' have an 'up' in them.
