ANSWER
b. On and left of the line x = 1.
Step-by-step explanation
The inequality is x less than or equal to 1. This means that the line x = 1 is included in the solution, which leaves us with options b or c.
To represent the values less than x = 1, we would take the values to the left of the line.
Hence, the region that represents the solutions of x ≤ 1 is on and left of line x = 1.
