Question

Click on the graph until the graph of a line with undefined slope appears.

Answer 1

The middle one is the answer

Answer 2

The graph with the vertical line.

Explanation:

All vertical lines have an undefined slope. Horizontal lines have zero slope, and diagonal lines have a slope.

When calculating a slope for a vertical line, you would have to divide by zero. The quotient of any number and 0 are undefined, as you cannot divide by zero. This is what makes vertical lines have an undefined slope.
