Question

Find the slope of the line connecting the points (-9,-2) and
(-9,-4)

Answer 1

Answer: Undefined

Explanation:

Our task is to find the slope of the line, given the following points:

• (-9,-2) and (-9,-4)

We can use the slope formula (below) to solve.

`m=\cfrac{y_2-y_1}{x_2-x_1}`

Substitute the values:

`m=\cfrac{-4-2}{-9-(-9)}`

Evaluate.

`m=\cfrac{-6}{0}`

`\sf{m=unde\,\!fined}`

Therefore, the slope of these two points is undefined.

Answer 2

m = Undefined

Explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)
Points: (-9,-2) and (-9,-4)

We see the y decrease by 2 and the x stay the same, so the slope is

m = Undefined
