#### Answer

The slope of the line is approximately $\dfrac{1}{2}$.

#### Work Step by Step

A line with a positive rises from left to right while a line with a negative slope falls from left to right.
The given line rises from left to right so its slope is positive.
The line appears to pass through the points $(-2, 0)$ and $(0,1)$.
We solve for the slope using the two points above and the slope formula:
$m =\dfrac{1-0}{0-(-2)}=\dfrac{1}{2}$
Thus, the estimated value of the slope of the line is $\dfrac{1}{2}$.
