![]() ![]() The first coordinate, the x-coordinate, will refer to the number which corresponds with the point's horizontal location as determined by the number on the x-axis.A point labeled (0,-5) is drawn five units below the origin on the y-axis.įor every point in the plane, we will identify the location using an ordered pair of the form (x,y). A point labeled (-4,0) is drawn four units to the left of the origin on the x-axis. A point labeled (-3,4) is drawn three units left and four units up from the origin. A point labeled (4,2) is drawn four units to the right and two units up from the origin. The quadrants are labeled with quadrant I (Roman numeral one) being the upper right region, quadrant II (Roman numeral two) being the upper left region, quadrant III (Roman numeral three) being the lower left region, and quadrant IV (Roman numeral four) being the lower right region. On the y-axis, the tick marks above the origin are labeled 1 through 5 going up and -1 through -5 going down as they get farther from the origin. ![]() On the x-axis, the tick marks to the right of the origin are labeled 1 through 5 and the tick marks to the left of the origin are labeled -1 through -5 as they get farther from the origin. The axes have 5 tick marks in each direction. These lines cross at the point labeled as the origin. The line labeled as the y-axis is drawn vertically. Image Description: The line labeled as the x-axis is drawn horizontally. We will refer to this point of intersection as the origin and give it coordinates (0,0), since the number zero will be the reference number on each axis.We will intersect these axes at the point where zero is located on each of them (as shown below).The other will be drawn vertically and labeled as the y-axis. ![]()
