Points on the coordinate plane examples. This is x is equal to negative 1, negative 2, negative 3, negative 4. Coordinate plane Coordinates ordered pairs. Let’s start with coordinates and figure out where those points are. We’ll figure it out first, but you always have to write it second. All right, let’s plot these on a graph, as they tell us to do.
Let me do it in a color that you’ll be able to read. So you have this point right here, A. Then we’ll do one more problem. Rearrange the parallelogram and the two smallest triangles to make a hexagon. Please submit your feedback or enquiries via our Feedback page. Negative 4, negative 4.
It’s 3, negative 4. Let’s do the y-coordinate first. They both have an x value of 3. If they’re both positive, you’re in the first.
They call this the first quadrant. Well, the point is going to have to be on the same vertical as this point.
Let’s plot these points. So point B, x is positive.

And you could have gone the other way. All right, let’s plot these on a graph, as they tell us to do. When we looked up at this stuff over here, these points are in the fourth quadrant. So that’s x equals 1, 2, 3, 4. So it’s going to have to be 3. eeureka
And we are done. Let me get another color. This is x is equal to negative 1, negative 2, negative 3, negative 4.
You just drop down. So it’s right above it.
It’s going to have to be on the same horizontal as that point. This is y is equal to negative 1, negative 2, negative 3, negative 4.

If just the y is negative, but the x is positive, you’re going to be in the fourth. It’s 1, lesspn, 3. Or if you’re given coordinates, how to figure out where to plot something on the x,y-coordinate plane. And then y is negative 4. You can use the free Mathway calculator and problem solver below to practice Algebra or other math topics. You always put the x-coordinate first. Then determine what the coordinates of the fourth point, D, would be.
And you’re still going to get to the same point. And then it’s going to have to be on the same horizontal as this point. And notice, both of these have the exact same y.
It is 5 to the left. A quadrilateral with only 1 pair of parallel sides. Right to the left of point C. And just to familiarize yourself with a labeling scheme that you may or may not have seen before, is that people label these sections of the coordinate plane. I could write that this lessom equals 4.
