Solve the inequation x lt - 3 graphically

Answer»

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