Given:
The inequality is
To find:
The solution of the given inequality on the number line.
Solution:
We have,
Subtract 5.25 from both sides.
Multiply both sides by -1 and change the sign of inequality.
The value of b always less than or equal to -1.25. Since -1.25 included in the solution set, therefore there is a solid circle on -1.25.
-1.25 lies between -2 and -1. It means the solid circle lies between -1 and -2.
, so the number line is shaded from the circle to negative 5.
A number line going from negative 5 to positive 5 is the required solution if a solid circle appears between negative 1 and negative 2. The number line is shaded from the circle to negative 5.
Therefore, the correct option is A.
