Answer
quadrants I and III.
Work Step by Step
We call the upper right quadrant as quadrant I, and count the others in the counterclockwise direction.
$\left[\begin{array}{ccc}II&|&I\\--&(0,0)&--\\III&|&IV\end{array}\right]$
Right of the y axis, x-coordinates are positive,
left of the y axis, x-coordinates are negative.
Above the x-axis, y-coordinates are positive
below the x-axis, y-coordinates are negative.
Both are positive in quadrant I,
both are negative in quadrant III.
