Question

Solution set of the inequality y ≥ 0 is ______.

Options

• half plane on the right of Y-axis including the points on Y-axis.

• half plane on the right of Y-axis excluding the points on Y-axis.

• half plane above the X-axis excluding the points on X-axis.

• half plane above the X-axis including the points on X-axis.

Answer 1

Solution set of the inequality y ≥ 0 is half plane above the X-axis including the points on X-axis..

Explanation:

Solution set of the given inequality is {(x, y) : y ≥ 0} i.e., the set of all points whose ordinates are non-negative.

All these points lie either on X-axis or above X-axis.
