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 Make a Figure Larger Using a Dilation?
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...

How Do You Make a Scatter Plot?
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.

How is a Function Defined?
A function means that every element of the domain is paired with exactly one element in the range. The teacher illustrates this by using a table for the given set of numbers.

What's the Inverse of a Relation?
The instructor shows how to write the inverse of a relation. In a set of ordered pairs, she takes each pair of coordinates and flips the order, getting the inverse.

How Do You Find the Domain and Range of a Relation?
A straightforward explanation of domain and range. The domain of a set of coordinates are the X-values, and then range are the Y-values of the set.

What's a Function?
There are many ways to represent a function. The main idea though is that for every input there is an output. Watch this video as the instructor illustrates and explains several different ways to show a function. She demonstrates domain...

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.

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's Negative Correlation?
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.

How Do You Use a Scatter Plot to Find a Line of Fit?
What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.

How Do You Graph an Exponential Function Using a Table?
One way to get values to be able to graph an exponential function is to make a table. This seems pretty straightforward. Set up a table to plug in random values for x. Then put those values into the equation to get the y-values. These...
