In which quadrant does the point (15,-7) lie?

The quadrant the given point (15,-7) lie is fourth  quadrant.

The first quadrant in Cartesian coordinate is given as;

= (x, y)

The second quadrant in Cartesian coordinate is given as;

= (-x, y)

The third quadrant in Cartesian coordinate is given as;

= (-x, -y)

The fourth  quadrant in Cartesian coordinate is given as;

=(x, -y)

(15,-7) corresponds to (x, -y)

Thus, the quadrant the given point lie is fourth  quadrant.

Quadrant 4

Step-by-step explanation:

Quadrant 1: Positive x and Positive y

Quadrant 2: Negative x and Positive y

Quadrant 3: Negative x and Negative y

Quadrant 4: Positive x and Negative y

For point (15, -7), we have a Positive x and a Negative y so it belongs in Quadrant 4.
