Answer: (-3, -1) and (-4, -6) are located in the third quadrant, and just so you know the answer you have selected already is wrong because that would end up in the fourth quadrant.
Step-by-step explanation: The third quadrant is in the bottom left corner and is to the left of zero on the X line which means that X has to be below zero and it is below zero for the Y also which means that the Y coordinate also needs to be below 0.
Hope this helps
