The image shows a line passing through the points $(-3, 0)$ and $(0, 3)$. To find the slope of the line, we use the slope formula:

$\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}$

Here, $(x_1, y_1) = (-3, 0)$ and $(x_2, y_2) = (0, 3)$. Substituting these values:

$\text{slope} = \frac{3 - 0}{0 - (-3)} = \frac{3}{3} = 1$

So, the slope of the line is $1$.

Here are some related questions you might find interesting:

1. What is the equation of this line in slope-intercept form?
2. How would the slope change if the line were steeper?
3. Can you calculate the y-intercept based on the graph?
4. What is the significance of a positive slope?
5. How do you find the slope if given only the graph and no points?

Tip: The slope tells you how steep a line is; a slope of $1$ means that for every unit increase in $x$, $y$ increases by exactly 1 unit.
