Graphing Data on a Coordinate Plane
When you have a long list of numbers, or data, it's sometimes difficult to understand what they mean. But we can reorganize that data in different ways, to help us out! In this video we're going to look at data in graph form - we'll plot...

Understanding the Basic Coordinate Plane
Let's join Sue on a treasure hunt! We have a treasure map ready and we know that the X sign marks the spot where the treasure is at, but how do we know how to describe its location on the map? Learning about what’s called the coordinate...

Learn how to construct the unit circle
👉 Learn about the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle intersects the x-...

How to Determine a Coordinate Value
In this short video we will answer a standardized math test question where we are asked to determine a coordinate value on a graph. We will learn that an ordered pair is written in the form (x, y) where x represents the x coordinate and...

What is the X-Coordinate?
How are ordered pairs, coordinate points, and graphing related to each other? What is the importance of the x-coordinate? Does it matter what order you write an ordered pair in? Yes! The x-coordinate is always written first. Always! And...

How Do You Find the X-Coordinate of a Point on a Line If You Have Another Point and the Slope?
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.

What Does Positive Slope Mean?
How can two negative values create a positive slope? Rise over run, a negative divided by a negative. Watch the instructor explain just how that works.

What Does Negative Slope Mean?
Rise over run? The instructor explains two ways that a slope can be negative. It's not as complicated as you may think. Follow along on this lesson and see for yourself.

How Do You Find the Y-Coordinate of a Point on a Line If You Have a Graph?
Looking at the graph of a given linear equation, find the y(4). What? What does that even mean, find y(4)? Watch this video and the teacher will show and tell everything about finding the y(4) from the given graph.

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.
