The change in x is 0, the slope is undefined. This means the line is vertical.

To find the slope of the line from the table, we can use the following formula:

Slope = (Change in y) / (Change in x)

Here's how to find the slope step-by-step:

Pick any two points from the table.

Write them as coordinate pairs in the form (x1, y1) and (x2, y2).

Substitute the values into the slope formula:

Slope = (y2 - y1) / (x2 - x1)

In this case, you can choose any two points from the table. Let's choose the first and second points:

Point 1: (5, -12)

Point 2: (5, -9)

Substitute the values into the formula:

Slope = (-9 - (-12)) / (5 - 5)

Slope = 3 / 0

As the change in x is 0, the slope is undefined. This means the line is vertical.
