What is the slope of the line that contains the points (-5,4)(-5,7)

 

Hello Duckielo!

 

\(m=\frac{y_2-y_1}{x_2-x_1}=\frac{7-4}{-5-(-5)}=\frac{3}{0}=\infty\)

 

\( The\ slope\ of\ the\ line\ is\color{blue}\ \infty.\)

\(The\ function\ straight\ is\ a\ vertical.\)

It could equally well be - infinity. 

So I would call it undefined.
