Hey there!
Knowing that you are given two points from the line, you can use the slope formula in order to find the slope of the line.
The slope formula is:

Your two points are:
(-1, -6) and (1,-2)
Now, plug the point values into the formula:

Now, simplify the expression:


=2
Therefore, the correct answer would be that you have a slope of 2, so choice A.
Hope this helps and I hope you have a marvelous day! :)
