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...

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.

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.

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.

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

The x-intercept is the point at which the line of the equation crosses the x-axis. The y-intercept is the point at which the line of the same equation crosses the y-axis. It's as easy as that. Look at your graph and note these locations.

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.

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...

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...

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.

The x-intercept is the point at which the line of the equation crosses the x-axis. The y-intercept is the point at which the line of the same equation crosses the y-axis. It's as easy as that. Look at your graph and note these locations.

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.

Watch this tutorial to learn about the y-intercept, the point where the graph of the line of a linear equation crosses the y-axis. [1:49]

Learn how to plot a point on a coordinate plane, identify the ordered pair, and figure out which quadrant the point is in. This video shows examples along with hints and tricks. [7:17]
