About this video
The video works through quick exercises where you check a list of coordinate pairs against a graph to find the one that is not plotted. It does this by locating each pair, such as (3, -2), (-4, 5) and (-8, 4), and seeing whether a point is there.
You'll be able to
- locate an ordered pair on the coordinate plane, including negative coordinates.
- check whether a given point appears on a graph.
- locate points that lie on an axis, like (-5, 0).
Key words
- coordinate pair
- Two numbers (x, y) that say where a point is on the plane.
- graphed
- Plotted as a dot on the coordinate plane.
Transcript
Consider the following coordinate pairs. And they give us a bunch right over here. Which of those pairs is not graphed below? So let's see, 3 comma negative 2. So 3 comma negative 2, well, actually, that looks like that first one is not graphed. So 3 comma negative 2 isn't graphed.
And you can verify that all of these others do seem to be graphed. 4 comma negative 8 is right there. Negative 8 comma 3 is right over here. 4 comma 6 is right there. And negative 1 comma 0 is right there. So let's do a couple more of these. So is negative 5 comma 0 graphed?
Yep. It's right over there. Negative 4 comma positive 5 should be there. So that's not graphed. So let me just select that one. Let's do one more of these. Negative 8 comma 4, so negative 8 comma 4, we got lucky. The first one is not graphed-- negative 8 comma 4.
And we're done.
