Graph description: Graph with X-axis labeled Y and the Y-axis labeled P. A single line with a negative slope starts near the top left corner of the graph and goes straight to the lower right corner at roughly a -45 degree angle. This line is labeled AD1. A second line, parallel to the first but shifted to the right, is labeled AD2. On the AD1 line, there are two points, labeled Point A and Point B. Point A is farther to the right than Point B.
Refer to the figure above. Holding all else constant, a decrease in the interest rate would be represented by a movement from __________.
AD1 to AD2
AD2 to AD1
point A to point B
point B to point A
