Suppose x is the height of a building and y is the number of rooms in the building. Which quadrant does the point (x, y) lie on?​

First quadrant.

Step-by-step explanation:

Quadrants:

In the first quadrant, both x and y are positive, that is, x > 0, y > 0.

In the second quadrant, x is negative while y is positive, that is, x < 0, y > 0.

In the third quadrant, both x and y are negative, that is, x < 0, y < 0

In the fourth quadrant, x is positive while y is negative, that is, x > 0, y < 0

In this question:

Both the height of a building, which is x, and the number of rooms in the building, which is x, have to be positive numbers, and thus, the point (x,y) lies on the first quadrant.
