Quadrant I (x, y) Quadrant II (-x, y) Quadrant III (-x, -y) Quadrant IV (x, -y) Where x and y are both positive numbers.
Any ordered pair in the third quadrant has negative x and y values. So (-1,-1), for example, is the third quadrant.
Quadrant I: Top Right: x positive, y positive Quadrant II: Top Left: x negative, y positive Quadrant III: Bottom Left: x negative, y negative Quadrant IV: Bottom Right: x positive, y negative
Quadrant I : (+, +) Quadrant II : (-, +) Quadrant III : (-, -) Quadrant IV : (+, -)

Consider angles in standard position, and note that for the equation sin θ = 0.5, the angle in the first quadrant is θ = 30° The sin function is positive in quadrants I and II, and negative in quadrants III and IV, so there are two basic answers, one in quadrant III and another in quadrant IV. In quadrant III, the angle is 180° + 30° = 210° In quadrant IV, the angle is 360° - 30° = 330° Of course, this is a wave function so there are an infinite number of answers. You can add full circles (i.e. multiples of 360°) to either of these answers to get more answers. In quadrant III, the angles are 210°, 570°, 930°, ... In quadrant IV, the angles are 330°, 690°, 1050°, ...

Y = - 2X - 3 Plot this and see that a line with a negative slope can go through quadrant III.
The x and y axes divide the plane into four quadrants. Quadrant I is North East Quadrant II is North West Quadrant III is South West Quadrant IV is South East
