If you remember from earlier chapters the domain contains values that correspond to the independent variable whereas the range contains values corresponding to the dependent variable. The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range. Coordinate pictures are a way of helping to reinforce plotting skills with a game of connect-the-dots. And then do the same but following a horizontal line to find the y-coordinate.Ī relation is a set of ordered pairs. Find worksheets about Coordinate Picture Graphing. Begin at the point and follow a vertical line either up or down to the x-axis. To find out the coordinates of a point in the coordinate system you do the opposite. And the y-coordinate tells you have many steps to move up (positive) or down (negative). The x-coordinate tells you have many steps you have to take to the right (positive) or left (negative). It's always a good idea to start at the origin. To graph a point one draws a dot at the coordinates that corresponds to the ordered pair.
