Answer:

the last option

Step-by-step explanation:

To verify if a line is a function, we use the vertical line test. This means that for evey x-value, there should only be one y-value.

For example, if 2 points were (-1,3) and (-1,5), draw a vertical line at the domain value. Because the line intersects 2 point, the 2 points wouldn't create a function.
