This is the first lesson of the Geometry course and it is about the coordinate plane, which should be a review. The plane is part of the coordinate system. It is made up by two axes (the x and the y-axis), and these two intersect at the origin. Also, these two are perpendicular. You'll see how the x-axis and the y-axis make up the four quadrants of the coordinate plane, and you'll learn about the ordered pairs. An ordered pair is when you have the x-coordinate paired with a y-coordinate, for example (4,2). In this lesson you are going to practice graphing in the coordinate plane, and you'll learn more about the collinear points.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
