What is the slope of the graph of the line x = - 1?

A.

0

B.

-1

C.

The slope is undefined.

D.

1

Slope is rise/run aka m/t how if it goes up m units, it goes to the right t units

x=-1

just a horizontal line

rise=0 since it doesn't go up at all

run=any number except 0

0/x=0

therefor slop=0

answer is A

The answer to your question is B. - 1
