Answer:

Step-by-step explanation:
For this case we have two points given (-1,6) and (1,5)
And we want to complete the point slope equation of the line:

We need to find the slope and we can use the following formula:

And replacing the info we got:

And then the equation would be given by:

And our final answer would be:

It is a function, so yes ig
Answer:
