Answer:
Explanation:
The slope is the ratio of rise to run.
Rise is the difference of y-coordinates, run is the difference of x-coordinates.
Now, the slope is said undefined if the difference of x-coordinates is zero.
It means you have to divide by zero but it is impossible.
We have a point (- 4, - 8) and the slope is undefined.
It means our line has repeat x = -4 coordinates, it is a vertical line.
Its equation will be:
