Question

What is the slope of the line that passes through the points (−4,−2) and (−4,−22)? Write your answer in simplest form.

Answer 1

undefined

Explanation:

1) y₂-y₁/x₂-x₁

2)-22 -(-2)/ -4 -(-4)

3) -20/0

4) slope is undefined so there is only one line (same x coordinate)

Answer 2

Undefined Slope

Explanation:

If we look at the points given, then we can see that the X coordinates are the same. Putting this into (y2-y1)/(x2-x1), we can see that the denominator would be 0, meaning the slope would be undefined.
