ANSWER and EXPLANATION
The measure of angle 1 is greater than 97° and at most 115° (that means less than or equal to)
This means that:

From the diagram, angle 1 is equal to (9x + 7). This is because they are alternate interior angles.
This therefore means that:

Solve for x:

Therefore, the number line graph of the possible range of values of x is:
That is the number line.
