Question

Find the slope of the line which goes through the given points.
d
A(2,8) and B(2,6)

Answer 1

Undefined

Explanation:

Use the formula:

`m=(y+2-y_1)/(x_2-x_1)`

Plug in the numbers/coordinates accordingly:

`m=(6-8)/(2-2)`

`m=(-2)/(0)`

m = undefined

When x = 0, the slope is undefined.

Answer 2

Undefined

Explanation:

A slope is found using the formula rise (change in y) over run (change in x). The change in x is 0, and the change in y is -2. The answer is -2/0, but dividing by 0 gives you undefined. Don't believe me? Look at the attached image.
