Find the slope of the line. On a coordinate plane, a line goes through (negative 1, 0) and (negative 1, 1).

a.
Undefined

c.
Three-halves

b.
0

d.
-1

Greetings.

A line goes through (-1,0) and (-1,1).

~ Theory ~

If both x-term for both ordered pairs have same value. The slope for line graph is undefined.

~ Proof ~

Using Rise/Run

Because the denominator is 0, therefore, the slope is undefined.

Because from rise/run. We put the x-term to subtract another x-term. And if both x-terms have same value. It will give the run/denominator = 0.

Therefore the answer is a. Undefined

I think the answer would be letter a
