7. What is the slope of the line through the points (2/3, 4/7) and (2/3 , 11/7)

undefined

Step-by-step explanation:

slope = change in y / change in x

Let's take change as (second point) - (first point). We could do (first point) - (second point), but we have to choose one

slope = (y₂-y₁)/(x₂-x₁)

          = (7/7)/(0)

           = 1/0

Anything divided by 0 is undefined, so the line has no slope/is undefined

70,000 + 6,000 + 800 + 30

step-by-step explanation:

good luck on your studies! : )
