the lowest number is -3 and as it goes on, the number gets bigger and bigger therefore x must be larger than -4 but <u>not</u> equal to it.
2) D
the largest number is 9 and as it goes on, the number gets smaller therefore x must equal to and less than 9.
3) D
the largest number is 0 and the arrows points towards the negative numbers and the solid dot tells us that x can be equal to the number therefore the x must be equal to or less than 0.
4) A
the smallest number is -6 and the arrow points towards the positive numbers and the open dot tells us that x does not equal that number therefore x must be greater than -6 but <u>not</u> equal to it.
