Lesson 17 Graph of an equation in two variables: - the set of all ordered pairs that make the equation true One of the most basic ways to graph an equation in two variables is to use an -chart. Graphing an equation in two variables using an -chart: 1. Select arbitrary inputs 2. Use the inputs to calculate outputs 3. List the inputs and outputs as ordered pairs 4. Plot the ordered pairs 5. Connect the points Example 1: Graph the following equation using an -chart 2 3 Input Output Ordered Pair ? ? ? , ? ? 2 2 3 ? 4 3 ? 1 ? 2 1 3 ? 2 1 ? 2 0 3 ? ? 2 1 3 ? 2 3 5

The points where a graph touches or crosses an axis are called intercepts. When a graph touches or crosses the -axis, what is the -coordinate of that point? -intercepts are written in the form , , where is a value on the horizontal number line. When a graph touches or crosses the -axis, what is the -coordinate of that point? -intercepts are written in the form , , where is a value on the vertical number line.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
