Answer
The slope is $\frac{1}{2}$.
Work Step by Step
To find the slope, we use the formula:
$$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$$
We now plug in points we find on the graph of the line into this equation to find the slope of this line. We will use the points $(2, 1)$ and $(0, 0)$:
$$m = \frac{1 - 0}{2 - 0}$$
Simplify:
$$m = \frac{1}{2}$$
