Solve the inequation `x lt - 3 `graphically

Explanation

We know that the graph of `x= -3` is a straight line AB drawn parallel to the y - axis at a distance of units to the left of the y- axis.

Clealy , the point (0,0) does not satisfy the inequation `,x lt -3 `
So we shade that part of the plane divided by AB which does not contain O(0,0) excluding AB.
The shaded Part of the plane is the solution set of `x lt -3 ` as shown above.
