Question

What is the slope of the line that passes through the points (-1, 1) and (-1, 4)? Write your answer in simplest form.

Answer 1

Answer: undefined

Explanation:

slope form:
`(y2 - y1)/(x2 - x1)`

simply plug in values

`(4-1)/(-1-(-1))`

`(3)/(0)`

Answer: undefined

you can also tell by realizing both x coords are the same, meaning the line is verticle and verticle lines' slopes are undefined
