Question

Use the slope formula to find the slope of a line that passes through M(3, 7) and N(3,-1). m =

Answer 1

the formula of the slope is

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

where (x2,y2) is a right point from (x1,y1)

on this case the points are the same distance, so we can use any order

`\begin{gathered} m=(-1-7)/(3-3) \\ \\ m=(-8)/(0) \end{gathered}`

the slope cannot be calculated because the division between 0 dosnt exist, and the line is a vertical line x=3

the line is
