Answer:

The slope is undefined

Step-by-step explanation:

You can find the slope by doing change in y/change in x.

Y changed by 12 units while x changed by 0.

12/0 is undefined, so the slope is as well (on a graph, the line would be vertical)

0 or undefined or infinity

Step by step explanation:

slope = y2 - y1 / x2 - x1

= 4 + 8 / 0 + 0

= 12 / 0

= 0
