The only number that will equal -1 on a number line is -1 .
its bout right there9 where there is a 9
X doesn't have to equal to 4, it can be equal to any real number really (as in, not i), the really important part is that Y is equal to both Positive and Negative Infinity, just like in a horizontal line Y can be equal to any real number, but, in this case, X has to be equal to both Positive and Negative Infinity.
No, 60 is not equal to -60. In mathematics, the sign of a number indicates its direction on the number line. The positive sign (+) indicates a number is greater than zero, while the negative sign (-) indicates a number is less than zero. Therefore, 60 and -60 have the same absolute value (60), but they are in opposite directions on the number line.
... equal to the number.
It means that is is less than or equal to that number.
You have to graph an inequality on a number line. For example, x>3.The number 3 on the number line gets an open circle around it, and a line is extended to all the other possible equations.There is an open circle if it is a "greater than or less than" sign, and there is a shaded circle if there is "greater than or equal to, or a less than or equal to" sign.

If it is 'less than' or 'greater than' or 'not equal' then use an open circle.If it is 'less than or equal to' or 'greater than or equal' then use the shaded circle.
> is greater than; with a line under it it is greater than or equal to < is less than; with a line under it it is less than or equal to
"less than or equal to". The symbol for less than is " < " and for less than or equal to it is < with a line under it
The graph is the set of all value of x that are less than or equal to 3, so you draw a line parallel to the number line, under the 3 and to the left of it (less than). Also, underneath the point three you draw a circle at the end o your line. Since it is less than or equal to you fill in that circle. Otherwise it would only be an outline circle.
The "less than" sign in mathematics is an arrow head pointing to the left. If the arrow head is pointing to the right, it is "more than." If there is a straight line under the left pointing arrow head, it means "less than or equal to" and if there is a straight line under the right pointing arrow head, it means "greater than or equal to." Think of a number line. If you are at any number and go to the left, you are subtracting numbers. If you head to the right, you are adding numerals.
an open circle on a number line means the answer is just less than or greater than (< or >), but a closed circle means the answer is less than or equal to, or greater than or equal to (< or > with a line under it)
Less than (<) Greater than (>) Equal to (=) Greater than or equal to (> but it has another horizontal line under it) Less than or equal to (< but it has another horizontal line under it) Not Equal to (= but with a / through it)
If it is a 'greater than' or a 'less than' then it's a dotted line. If 'less than or equal' or if it's a 'greater than or equal' then it's a solid line.
