Question

What is the slope of the line through (-9,6)(−9,6)

Answer 1

slope is indeterminate

Explanation:

Given (- 9, 6) and (- 9, 6) ← that is a single point

No line is formed by a point , thus the slope is indeterminate

Answer 2

Well I think It's undefined

Explanation:

m = y2 - y1/x2 - x1

= 6-6/-9-(-9)

= 6-6/-9+9

m = 0/0
