Answer:
m = undefined
General Formulas and Concepts:
Algebra I
- Vertical Line Test - Tells us if a graph is a function
- Vertical Lines - slopes are undefined
Step-by-step explanation:
If the slope m was equal to 0, then it would be a horizontal line rather than a vertical line.
Using the Vertical Line Test, we also know that the graph is not a function.
Usually a vertical line has an undefined slope, as x equals a certain number, and m = unknown.
