Question

Find the slope of the line passing through (3,-4) and (3,8)

Answer 1

To find the slope ⇒ we must know the formula

Formula =
`(y2-y1)/(x2-x1)`

• (x1, y1) ⇒ (3, -4)
• (x2, y2) ⇒ (3,8)

Now let's solve and plug the known variables

Slope =
`(8-(-4))/(3-3) =(12)/(0)`

Nothing can be divided by zero

⇒ in this case, the slope is undefined

*interesting fact: the line is vertical

Hope that helps!
