What's a Boundary?
Are you graphing an inequality? What's that dashed line called? It's called a boundary line and it is the line that separates the coordinate plane into two separate half planes.

How Do You Graph Ordered Pairs in Each Quadrant?
Draw a graph, label your units, make a table of your given coordinates. Now plot your points, label each point as you graph it. Next identify the quadrant that each point is in and add that to your table.

How Do You Graph Points in the Coordinate Plane?
So you have an ordered pair and you want to graph it. Just remember that the first value is plotted along the x-axis and the second value in the pair is plotted along the y-axis. So count left or right, then up or down and you have...

How Do You Use a Graph to Reflect a Figure Over the X-Axis?
A reflection is just what you think it is, a mirror image. So how do you reflect a figure on a graph? Just flip it over. The teacher illustrates how to select a line of reflection (the x-axis) and make the calculations to flip the figure.

What Does Direct Variation Look Like on a Graph?
In a graph of a direct variation, the line must pass through the origin, (0,0). See the teacher illustrate what that looks like on a graph.

How Do You Check if a Point is on a Line If You Have a Graph?
The instructor demonstrates how to verify that a given point does or does not lie on the line of a given equation. She draws a graph (the axis lines need arrow ends) and plots the given linear equation. She then plots the coordinate...

How Do You Use Coordinates to Translate a Figure Vertically?
Transform the figure six units vertically down. Use the given coordinate points to translate by subtracting 6 from each of the given y-values. Then plot the new coordinates points and connect the dots.

How Do You Use Coordinates to Translate a Figure Horizontally?
There are many ways to transform a figure on a coordinate plane. This problem requires the movement to be four units horizontally to the right. Using the original coordinate pairs, a positive 4 can be added to each x-value to get the new...

How Do You Use a Graph to Translate a Figure Diagonally?
This presentation is pretty straightforward in illustrating how to translate a figure on the coordinate plane. Watch the instructor follow the directions to translate the figure four units to the right and six units down.

What is a Plane?
It's a bird, it's a plane, it's Superman. No, it's really a plane. A plane is named by identifying three points with the exception that they do not form a straight line. A plane can also be identified by a single letter naming it. The...

What is an Ordered Pair?
An ordered pair is comprised of an x-value, and a y-value. The x-value always comes first, then the y-value in an ordered pair. This ordered pair represents a point on a coordinate plane. There are many meanings of an ordered pair and...

What is the Coordinate Plane?
Just a quick diagram and explanation of the parts of the coordinate plane. You might want to remind your class to put arrows on the ends of the x-axis and the y-axis, as these lines go on forever.

What are the Coordinate Axes?
The coordinate axes are the x-axis, which is the horizontal axis, and the y-axis, which is the vertical axis. Remember, these axes go on forever.

How Do You Find the Midpoint Between Two Coordinates?
You've been given two coordinate points on a graph. When these points are connected they form a line segment. Now you have to find the midpoint of this line. Of course there is a formula and all you have to do is plug in the coordinate...

What are the Endpoints of a Line Segment?
A simple video on how to identify the endpoints of a line segment. Have your class watch this video to clarify any confusions about endpoints. This could be used as extra help for learners who are having difficulty, or as a supplement to...

What is a Vector?
Define a vector and teach your class about the different parts of a vector with this video. An instructor conveys what a vector is, labeling the parts and providing multiple examples. Learners can re-watch this video if they are...

How Do You Use a Graph to Translate a Figure Vertically?
Transformations. Learn a little bit of geometry. See how to translate a geometric figure on a coordinate plane vertically by sliding it over. Simply pick a point on the figure and count the units you want to move it. Then repeat that for...
