Math 1310 Class Notes – Section 1.3, Page 1 of 5 Math 1310 Section 1.3 Graphing Equations One of the things you need to be able to do upon completion of this course is to graph many types of equations. There are many methods to use. In this section, we’ll create a table of values and ordered pairs, and then plot the points in the coordinate plane. Once we have the points plotted, we can connect the dots to get a good picture of the equation. We need to be able to determine if a point that we’re given lies on the graph of a specific equation. Example 1: Determine which of the points (3, 2), (-1, 3) and (0, 2) are on the graph of the equation . 6 3 4 = - y x

Math 1310 Class Notes – Section 1.3, Page 2 of 5 When graphing an equation, it is usually very helpful to find the x intercept(s) and the y intercepts of the graph. An x intercept is the first coordinate of the ordered pair of a point where the graph of the equation crosses the x axis. To find an x intercept, let y = 0 and solve the equation for
