Yes.. See related link for an example.
Y = - 2X - 3 Plot this and see that a line with a negative slope can go through quadrant III.
Yes, the slope of a line that passes through quadrant 3 is typically negative. In quadrant 3, both the x and y coordinates are negative, so when you calculate the slope using the formula (change in y / change in x), the result will be negative. This is because as you move from left to right along the line, the y-values decrease as the x-values also decrease, resulting in a negative slope.
Quadrant I: x positive, y positive. Quadrant II: x negative, y positive. Quadrant III: x negative, y negative. Quadrant II: x positive, y negative.

The tangent function is equal to the sine divided by the cosine. In quadrant III, both sin and cos are negative - and a negative divided by another negative is positive. Thus it follows that the tangent is positive in QIII.
Quadrants I and III. In Quadrant I, the values are both positive. In Quadrant III, the values are both negative.
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

The top left quadrant is II (2) (x is negative, y is positive) The top right quadrant is I (1) (x is positive, y is positive) The bottom left quadrant is III (3) (x is negative, y is negative) The bottom right quadrant is IV (4) (x is positive, y is negative)
y is positive in quadrants I and II and negative in III and IV.
Any ordered pair in the third quadrant has negative x and y values. So (-1,-1), for example, is the third quadrant.
Sometimes they do, sometimes they don't.It depends upon which quadrant the point is in:In quadrant I they both have the same sign - positive;In quadrant II they have the different signs - x is negative whilst y is positive;In quadrant III they both have the same sign - negative;In quadrant IV they have the different signs - x is positive whilst y is negative;
