It is the point where the x-axis and y-axis intersect. ordered pair An ordered pair, gives the coordinates of a point in a rectangular coordinate system. linear equation An equation of the form where A and B are not both zero, is called a linear equation in two variables. Glossary horizontal line A horizontal line is the graph of an equation of the form The line passes through the y-axis at intercepts of a line The points where a line crosses the x-axis and the y-axis are called the intercepts of the line. Together you can come up with a plan to get you the help you need. See your instructor as soon as you can to discuss your situation. You should get help right away or you will quickly be overwhelmed. This is a warning sign and you must address it. Is there a place on campus where math tutors are available? Can your study skills be improved? Who can you ask for help? Your fellow classmates and instructor are good resources.
It is important to make sure you have a strong foundation before you move on. In math every topic builds upon previous work. All materials are downloadable and printable. Lesson plans, printable foldable, an assignment,answer keys, and the lesson presented in SMART Notebook are all included. This must be addressed quickly because topics you do not master become potholes in your road to success. This comprehensive package covers a lesson on graphing coordinates on all four quadrants using a shutter foldable. What did you do to become confident of your ability to do these things? Be specific. Reflect on the study skills you used so that you can continue to use them. Congratulations! You have achieved the objectives in this section. Ⓐ After completing the exercises, use this checklist to evaluate your mastery of the objectives of this section.Ĭonfidently. In this figure, we have graphed a horizontal line passing through the y-axis at 4. We’ll use 0, 2, and 4 for the x-coordinates. Fill in 4 for all the y’s in (Figure) and then choose any values for x. What if the equation has y but no x? Let’s graph the equation This time the y-value is a constant, so in this equation, y does not depend on x. Notice that we have graphed a vertical line. Plot the points from the table and connect them with a straight line. But to fit the points on our coordinate graph, we’ll use 1, 2, and 3 for the y-coordinates. Since x does not depend on y, you can choose any numbers you like. So to make a table of values, write in for all the x-values. No matter what is the value of y, the value of x is always The equation says that x is always equal to so its value does not depend on y. Let’s consider the equation This equation has only one variable, x.
This changes how we make a table of values to get the points to plot. They may have just x and no y, or just y without an x. Some linear equations have only one variable. This way we will avoid fractional answers, which are hard to graph precisely. But the arithmetic is easier if we make “good” choices for the values of x. When an equation includes a fraction as the coefficient of, we can still substitute any numbers for x. Look at the difference between these illustrations. This tells you something is wrong and you need to check your work. If you use three points, and one is incorrect, the points will not line up. If you only plot two points and one of them is incorrect, you can still draw a line but it will not represent the solutions to the equation. It is true that it only takes two points to determine a line, but it is a good habit to use three points. Extend the line to fill the grid and put arrows on both ends of the line.
