what is the slope

slope is undefined

Step-by-step explanation:

The slope is the difference in y divided by the difference in x.

That is the 2nd point's value minus the first, where the points are (x1, y1) and (x2, y2)

Given these 2 points, calculate the slope:

In this case, the slope is undefined. A function cannot have multiple outputs for the same input, and an undefined slope has infinite outputs for 1 input. You can see that in the attached image, it's a vertical line.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
