Question

Using the given points, determine the slope.

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

slope = -5
slope = 0
slope is undefined

Answer 1

Answer:

slope is undefined

Step-by-step explanation:

We can use the slope formula

m = (y2-y1)/(x2-x1)

   = (-4 -1)/(8-8)

     = -5/0

We cannot divide by zero so the slope is undefined

Answer 2

Answer:

Slope is undefined .

Step-by-step explanation:

• (8, 1)
• (8, -4)

        y2 - y1

m =   ---------------  

         x2 - x1

           -4 - 1             -5

m =   ---------------  =  ----- -  = 0

            8 - 8             0
