Question

Find the slope of the line that passes through the points (-6,-8) and (-6,12)

Answer 1

Answer:

Undefined

Step-by-step explanation:

m = Δy / Δx

m = (12 − -8) / (-6 − -6)

m = 20 / 0

m = undefined

The slope is undefined.

Answer 2

Answer:

The slope is 0. However, it is a horizontal line where x=-6.

Step-by-step explanation:

Use the equation m= y2-y1/x2-x1 to get 12--8/-6--6. Two negatives means a positive, so you get 20/0. This means there is no slope, because you cannot divide by 0. However, you notice that both x-values are -6, so you can safely assume that there is a horizontal line where x=-6.
