To find the unit rate from the graph, I will first determine the slope of the line. The slope represents the rate of change between $y$ and $x$, or the "unit rate" in this context. The slope formula is:

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

Step-by-Step Process:

1. The line passes through the origin $(0, 0)$.
2. Another point on the line is $(6, -6)$.

Using these two points, the slope is:

$\text{slope} = \frac{-6 - 0}{6 - 0} = \frac{-6}{6} = -1$

Thus, the unit rate of the graph is $-1$, meaning for every 1 unit increase in $x$, $y$ decreases by 1.

Here are 5 related questions you might find helpful:

1. What does the negative slope of a line represent in real-world situations?
2. How do you calculate the slope if the points are not integers?
3. How would the graph change if the slope were positive?
4. What is the difference between slope and unit rate in a linear equation?
5. How do you determine if a line is steep or shallow based on its slope?

Tip: The slope is often referred to as the "rate of change," which tells us how $y$ changes in relation to $x$.
