Step-by-step explanation:
Answer:

factorise out a and x :

but from general factorization:

a » x
b » 2
therefore:

In order to draw x ≤ -10 on a number line, first draw a closed dot at -10. This is because we have a ≤ and not a <. If we had a <, it would be an open dot.
Next, since we want x to be smaller, draw an arrow pointing towards all numbers that are smaller. This arrow would point to the left.
