Here is the 2D graph with the four different slopes labeled with the name "Olivia" for each type: positive, negative, zero, and undefined.

Let me know if you'd like more details or have any questions about the graph!

Additional Questions:

1. What is the mathematical definition of each type of slope?
2. How can you determine the slope of a line from its equation?
3. Can you calculate the slope of a line given two points?
4. How do you identify a horizontal or vertical line from its equation?
5. How do slopes impact the graph of linear equations?

Tip: When calculating the slope between two points, use the formula: $m = \frac{y_2 - y_1}{x_2 - x_1}$, where $m$ is the slope, and $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the points.
