Question

Using the given points, determine the slope.

(8, 1) and (8, -4)

Answer 1

-4 - 1 = -5
8 - 8 = 0
Undefined

Answer 2

Indeterminate

Explanation:

To find the slope of a line we have the next expression:

`m=(y_2-y_1)/(x_2-x_1)`

Now ve have the next two points (8, 1) and (8, -4) then:
`x_1=8,\,\,x_2=8,\,\,y_1=1` and
`y_2=-4,\,\,`

Then:

`m=(y_2-y_1)/(x_2-x_1)=(-4-1)/(8-8)=(-5)/(0)`

Because we can not divide by 0 the slope is indeterminate.
