Question

Don't understand please help it a number lines galore

Answer 1

1. x<3
x is less than 3, so the number line should be open circle and going to the left because left is less.

2.n less than or equal to -2
if it has an equal to with the < sign, then the circle needs to be filled in and less would be arrow going to the left.

now just look at the rest and read them the same way.  Greater than goes to the right. if there's an equal sign with it, then the circle must be filled in and not open. 

Hope this helps.
