Where is (0,19) located? Quadrant I Quadrant II Quadrant III Quadrant IV X-axis Y-axis
12345 [234]
Let P(a, b) be a point on the coordinate plane. Then the following hold:


i) If a>0, b>0 then P is in the I.Quadrant.

ii) If a<0, b>0 then P is in the II.Quadrant.

iii) If a<0, b<0 then P is in the III.Quadrant.

iv) If a>0, b<0 then P is in the IV.Quadrant.

v) If a=0 and b is positive or negative, then P is on the y-axis.

vi) If b=0 and a is positive or negative, then P is on the x-axis.


Since we have: a=0, and 19 positive, then this point is on the y-axis.


Answer: y-axis
