Quiz on Basic Graphing
In the coordinate plane, or the rectangular coordinate system, the vertical y-axis and the horizontal x-axis intersect at a point called the origin.
This section will help you better understand the coordinate plane and how to graph points on the plane.
When graphing, the coordinate plane will be labeled with "tick marks" denoting the scale. Beginning at the origin, count along the x-axis scale until you find the tick mark labeled with the x-axis coordinate of your point, and then count along the y-axis scale until you find the tick mark labeled with the y-axis coordinate of your point. That is the location of your point!
However basic this seems, it is a necessary skill for graphing lines and other equations.
This section will help you to understand how to better graph linear equations.
When graphing linear equations, "plugging in points" is a suggested method of solving the equations and putting them in a graphical format. To plug in points, select an x-coordinate (be reasonable in the number you select for the x-coordinate) and put the x-axis coordinate in the equation in place of x. Then solve the equation. This will give you a y-value. Put your chosen x-value and the y-value you solved for together, and you will have an ordered pair (a point) that you can graph. Repeat this process about 4 or 5 times and then connect the points you have graphed. The line you see will be the graph of a linear equation.
