Option (a)

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. Notice that in the given line, from the point $(-2, 0)$ to the point $(0, 2)$, the change in $y$ is $2$ and the change in $x$ is also $2$. This means that the slope of the line is $\frac{2}{2}=1$ Thus, the answer is Option (a).
