Use the slope formula to find the missing coordinate. You've been given all the needed information to solve this problem. So all you need to do is plug in the values and solve for the missing variable value.

A clear introduction to slope-intercept form, this would be helpful for learners who are struggling with this concept. You might also provide this instructional video for class members to use as they work on homework or class work. A...

Draw a graph, label the units, plot the given point, then draw a straight line up and down through the given point. That is now the graph of a vertical line through a given point.

Trying to write the equation for a horizontal line given an ordered pair? Just keep in mind that a horizontal line is all about the y value in the ordered pair. Plain and simple! Whatever the y value is in the ordered pair becomes the...

One way to solve a system of equations is to graph two equations and find the point of intersection. This method is demonstrated on a whiteboard to help your mathematicians understand the concept. An easy way to check your solution is...

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...

Explore linear equations with this video about lines with equal signs! The instructor demonstrates linear equations in a variety of ways: writing examples, plugging in solutions, and graphing equations. This resource could act as an...

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,...

Show your class how to rotate a figure 90 degrees clockwise around the origin of a coordinate plane. The lecturer in this video explains the concepts and steps involved in reflecting a figure across the y-axis. Consider providing this...

Pupils who view this tutorial will gain a better understanding of how to rotate a figure around the origin of a coordinate plane. This video covers how to rotate clockwise and counterclockwise to achieve the same purpose. Show this video...

Demonstrate how to rotate a figure around the origin of a coordinate plane. The instructor in this video tutorial explains the concept deliberately, showing how to complete the rotation as she presents the information. After she finishes...

Are you working on the distance formula? Derive the distance formula and help your learners by showing them the logic behind the distance formula. This practical video should help conceptual understanding and is appropriate for in-class...

Use a table to find the solution set for an equation. Watch an instructor as she directs how to create ordered pairs using a given domain and check your answers using one of these ordered pairs. A practical video for anyone, student or...

A clear introduction to slope-intercept form, this would be helpful for learners who are struggling with this concept. You might also provide this instructional video for class members to use as they work on homework or class work. A...

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.

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.

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...

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...

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.

So you've got some x-values and some y-values and you want to make a scatter plot. First thing is to make a table for your x and y values. Then make ordered pairs and you can plot them.

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

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.

Are you befuddled after reading this word problem? Not only is it a word problem but there are two variables, and not only does it have two variables, but it is an inequality. Don't pull your hair out! Take a deep breath and watch this...

In a linear equation, the y-intercept is really just the point where the graph of the line crosses the y-axis.
