This problem wants us to choose the linear inequality that matches the graph that we see.
00:05
And when we're looking at our graph, a lot of the characteristics we're going to look at is what we see when we're looking at the form of the slope intercept form, which is why normally equal to mx plus b when you're dealing with an equation, our equal sign will not be equal.
00:20
It will be an inequality.
00:21
And it looks like all four choices have a less than.
00:24
So we can kind of pencil that in as the only choice for our right answers.
00:27
But what we're going to look at now is what the slope and the y intercept is of our inequality line.
00:33
And the first thing we can look at very easily is the y intercept where we're crossing the y axis.
00:38
That's occurring at y equals 4, which means our b value is equal to 4.
00:44
So we can eliminate b because it has a y intercept of negative 2, and we can eliminate c because it has a y intercept plus 2.
00:52
So we're already down to a 50 -50 choice, either a or d...
