Which of the following describes a supply curve? Graph charts price on the x-axis and quantity on the y axis. As the price increases, quantity increases. The data points slope upward from left to right. The data plots charted are as follows from left to right: ($1, 10), ($2, 30), ($3, 50), ($4, 70), ($5, 90), ($6, 110), ($7, 130), ($8, 150), ($9, 170) The curve is upward sloping but quantity and price are not on the right axis. A graph charts quantity on the x-axis and price on the y-axis. Data points descend from left to right. As quantity increase, price decreases. The points on the graph from left to right are as follows: (20, $900), (30, $800), (40, $700), (50, $600), (60, $500), (70, $400), (80, $300), (90, $200), (100, $100) Price Quantity $1 100 $2 90 $3 80 $4 70 $5 60 $6 50 $7 40 $8 30 $9 20 Price Quantity $1 50 $2 100 $3 150 $4 200 $5 250 $6 300 $7 350 $8 400 $9 450
