What is the slope of the line shown in the graph?

A coordinate plane is shown. Points are graphed at 3 comma 2 and 1 comma 1. The points are connected by a line.

The slope of a line can be calculated using the formula:

Slope = (y2 - y1) / (x2 - x1)

Using the points (3, 2) and (1, 1), we can plug the values into the formula:

Slope = (1 - 2) / (1 - 3)
Slope = -1 / -2
Slope = 1/2

Therefore, the slope of the line shown in the graph is 1/2.
