Math 1310 Section 1.1: Points, Regions, Distance and Midpoints In this section, we’ll review plotting points, graph horizontal and vertical lines, some inequalities. Develop a formula for finding the distance between two points in the coordinate plane and one for finding the midpoint of a line segment with given endpoints. Graphing Points and Regions Here’s the coordinate plane: As we see the plane consists of two perpendicular lines, the x-axis and the y-axis . These two lines separate them into four regions, or quadrants. The pair, ( x , y ), is called an ordered pair . It corresponds to a single unique point in the coordinate plane. The first number is called the x coordinate , and the second number is called the y coordinate . The ordered pair (0, 0) is referred to as the origin . The x coordinate tells us the horizontal distance a point is from the origin. The y coordinate tells us the vertical distance a point is from the origin. You’ll move right or up for positive coordinates and left or down for negative coordinates.
Example: Plot the following points.
