Question

What is the answer to this problem?

Answer 1

The slope of a line is
`(dy)/(dx)`

where
`d` is the difference and
`y` and
`x` are the values.

In this case, the difference in
`y` is 10 and the difference in
`x` is 0

And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the
`y` axis.
