For a good time solve this shmoopy question.

00:05

Which inequality is expressed by the number line here?

00:08

Here are your options...

00:12

It's asking us to graph an inequality on a number line.

00:16

So let's start by looking at the dot or point on a number line to see which

00:20

number goes

00:21

in are inequality. The dot is between 0 and 1,

00:25

about halfway, so there's got to be a half

00:29

in our answer...which automatically eliminates A and B. The number line graph has

00:33

a dot that's filled not

00:35

an open hole, which means

00:37

we need an inequality with a greater than or equal to

00:41

or less than or equal to. Only C has that key equals

00:46

to underneath the inequality. So C is our answer.
