Question

Find the slope of the line passing through each of the following pairs of points. (−3, 9), (−3, −5

Answer 1

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-3, 9) and (-3, -5). Substitute:

$m=\dfrac{-5-9}{-3-(-3)}=\dfrac{-14}{-3+3}=\dfrac{-14}{0}\qquad\large{!!!!}\\\\\large\boxed{\text{Division by 0}}!!!$

Conclusion: The slope is not exist.

Given line is a horizontal line. Horizontal line has not a slope.

Answer 2

Answer:

Undefined Slope

Step-by-step explanation:

Well, we can first do (-5-9)÷[-3-(-3)].

We get -14/0.

We know anythingn divided by zero is impossible or undefined, so the answer to this is just undefined. If you can't enter it in your homework portal, then ask your teacher. Please don't report this, as I'm correct. Thank you!
