Answer:
the number line for
x≤-2
must include the values of the line less than -2 but also equal to -2.
When we are including the extreme number (in these case the -2) in the number line we must draw a filled circle (as seen in the attached image) to represent the symbol '≤'.
And the number line for
x<-5
must include all the numbers less than -5, except the -5 because of the sign < that means we are not including the extreme number (-5), so for this case in the number line we have an empty circle no represent the symbol '<'
