In which quadrants is the ordinate positive?
I and IV
II and III
I and II
The ordinate is the y-coordinate, so when the ordinate is positive, it means the y-coordinate is positive.
In Quadrant I, both the x-coordinate and y-coordinate are positive.
In Quadrant II, the x-coordinate is negative and the y-coordinate is positive.
In Quadrant III, both the x-coordinate and y-coordinate are negative.
In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative.
Therefore, the quadrants where the ordinate (y-coordinate) is positive are Quadrant I and Quadrant II.
