![]() ![]() We account for this on the graph by sketching a picture of a graph suggested by the points plotted. Recall that when a function is defined by an equation, we have a lot of inputs for \(x\) to choose from. One number line is horizontal and is called the x-axis. And you can see it divides a coordinate plane into four sections. ![]() Draw the function by connecting the dots. So this right here is the x-axis and this up-down axis is the y-axis. Use the ordered pairs to plot the graph of the function. And when we talk about the sections, were talking about the sections as divided by the coordinate axes. pictures can be just as valuable in helping us. The coordinate plane is a two-dimension surface formed by two number lines. A quadrant are each of the four sections of the coordinate plane. Review graphing points on a coordinate plane, and try some practice problems. Draw the function by connecting the dots. Chapter 6 Graphing Linear Functions In This Chapter Understanding the coordinate plane.Use the ordered pairs to plot the graph of the function.Create ordered pairs from the inputs and their outputs add to table. ![]() Compute the outputs \(f(x)\) corresponding to each input \(x\) by plugging the \(x\) value into the rule for \(f(x)\) add these to the table.Choose several inputs to use to create ordered pairs convenient numbers such as -1, 0, 1 are good to include, and often times, 4-5 points is sufficient to get an idea of what the graph will look like.Create a table to keep track of inputs, outputs, and ordered pairs.Graphing paper, coordinates worksheets and answer keys are included. For a fun bulletin board display, instruct students to be creative and color the picture however they like and then hang the completed pictures on your board or wall. To graph a function defined using an equation for its rule This activity is perfect for math centers, early finishers or homework. ![]()
