Question

Solve graphically: x ≥ 0 

Answer 1

Consider the line whose equation is x = 0. This represents the Y-axis.

To find the solution set, we have to check any point other than origin.

Let us check the point (1, 1)

When x = 1, x ≥ 0

∴ (1, 1) lies in the required region

Therefore, the solution set is the Y-axis and the right side of the Y-axis which is shaded in the graph.
