quadranti
o quadrant ii
o quadrant iii
o quadrant iv

Quadrant IV

Step-by-step explanation:

Quadrant I = (+ , +)

Quadrant II = (- , +)

Quadrant III = (- , -)

Quadrant IV = (+ , -)

(1/2 , -1.8)

1/2 is +

1.8 is -

(+ , -)

It lies on Quadrant IV

Quadrant IV

Step-by-step explanation:

Quadrant I    top right  (+,+)

Quadrant II      top left ( - , + )

Quadrant III  bottom left  ( -, - )

Quadrant IV  bottom right (+,-)

  Since x is positive and y is negative, (1/2, -1.8)  is in Qudrant IV (bottom right)

i believe the correct answer is b.
