Answer:
first and third quadrants
the answer B
Step-by-step explanation:
on the first quadrant x and y are both positive
in the second one x is negative and y positive so -x/y=-1
on the third quadrant x and y are both negative
so -x/-y=1
on the fourth quadrant x is positive and y negative so
x/-y=-1
here, in all cases x and y are taken the same length that's why we take always 1 or -1
