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.

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...

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.

Perform a reflection of a figure over the y-axis. This seems pretty straightforward. But also learn how to use the coordinates to reflect a figure.

Perform a reflection of a figure over the x-axis. This seems pretty straightforward. But also learn how to use the coordinates to reflect a figure.

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...

There are several ways to determine if an ordered pair is the solution to a linear equation. The ordered pair can be plugged in to the equation to check if it's a solution. However, in this video the instructor sets up a table and plugs...

Line of reflection is basically a geometry term used in the transformation of figures. It identifies the line on the graph that you reflect a figure over. The line can be vertical, horizontal, and diagonal. Actually, it can be any line...

A dilation increases or decreases the size of a figure. In this lesson the teacher shows you how to use a scale factor of three to dilate the given figure. She identifies the ordered pairs, multiplies them by three, plots the new...

Translating the graph of an absolute value equation horizontally based on the value of a constant, seems to be a big task. That sentence was a mouthful. So what does it all mean? Click on this video to observe the instructor illustrate...

Watch this video and find out how to graph a quadratic equation when it's in intercept form! After going through the different forms of quadratic equations, an instructor leads viewers through an example problem. For the example problem,...

Making a table for a quadratic function is not so complicated. Here are a few tricks to make it easier. One trick is to find the axis of symmetry and another is to find the vertex. These two values can be used to pick values to plug in...

Watch this video to learn how to find the solution to a system of equations with the substitution method! A teacher will lead you through each step necessary, explaining her steps and the reasoning behind her decisions. After watching...

Since the focus of this video is on explaining the solution to a system of equations, the lecturer does not work through the problem. Instead, she points out that the solution should be an ordered pair that makes each equation a true...

You have been given the value for the y-intercept and the slope of a line. Now you have to graph it. So draw a graph, plot your y-intercept and then count out your movement for slope. Don't forget to connect the dots and draw a line...

How can a value of x and y satisfy a solution to two equations? It doesn't seem possible. Given a system of linear equation, find a solution that satisfies both equations. It can be done. In this video, the instructor demonstrates how to...

A very short explanation of what makes a relation: a set of ordered pairs.

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...

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.

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.

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...

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...

There are many ways to solve a quadratic equation. Let's check out how to solve a quadratic equation by graphing. But first, let's find the axis of symmetry and the vertex before making a table of values. Write the values as ordered...

If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.
