Review of Cartesian Plane
The Cartesian Coordinate System is a system for representing points on a plane in relation to an x-axis and a y-axis whose point of intersection is labelled (0, 0). This point is referred to as the origin. The Cartesian plane is broken up into four quadrants.
Coordinates on a graph are given in the format (x, y) where the x-value, which is listed first, indicates the horizontal location and the y-value indicates the vertical location.
State the coordinates of points A, B, C, and D found on the graph.
Point A, (3, 7), is located in quadrant 1 where both the x and y-values are positive. Point A is 3 units to the right of the origin, (0, 0), and 7 units above the origin.
Point B, (–2, 4), is located in quadrant 2 where the x-values are negative and the y-values are positive. Point B is 2 units to the left of the origin, (0, 0), and 4 units above the origin.
Point C, (–1, –3), is located in quadrant 3 where both the x and y-values are negative. Point C is 3 units to the left of the origin, (0, 0), and 1 unit below the origin.
Point D, (6, –5), is located in quadrant 4 where the x-values are positive and the y-values are negative. Point D is 6 units to the right of the origin, (0, 0), and 5 units below the origin.
Point B, (–2, 4), is located in quadrant 2 where the x-values are negative and the y-values are positive. Point B is 2 units to the left of the origin, (0, 0), and 4 units above the origin.
Point C, (–1, –3), is located in quadrant 3 where both the x and y-values are negative. Point C is 3 units to the left of the origin, (0, 0), and 1 unit below the origin.
Point D, (6, –5), is located in quadrant 4 where the x-values are positive and the y-values are negative. Point D is 6 units to the right of the origin, (0, 0), and 5 units below the origin.
