Question

Find the slope of the line that passes through (-6, -2) and (-7, -2)

Answer 1

`0`

Explanation:

We could use the Slope Formula to find the answer, but there's an easier way of doing it. Notice that the y-coordinates of both points are the same. This means that the line that passes through these points is horizontal, which makes our answer
`0` because all horizontal lines have a slope of
`0`.

All horizontal lines have a slope of
`0` because the value of y never changes as the value of x changes, so if we were to input any two points on a horizontal line into the Slope Formula, our numerator would be
`0` (because anything subtracted from itself is
`0`), leaving us with a result of
`0` regardless of the denominator since
`0` divided by anything is
`0`. Hope this helps!
