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 `cancel<=` 0
∴ (1, 1) does not lie in the required region.
Therefore, the solution set is the Y-axis and the left side of the Y-axis which is shaded in the graph.
