ACartesian planeis a graph with one x-axis and one y-axis (that’s why it’s sometimes called an X Y graph). These two axes are perpendicular to each other. Theorigin(O) is in the exact center of the graph. Numbers to the right of the zero on the x-axis are positive; numbers ...
Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is:The point (12,5) is 12 units along, and 5 units up.Four QuadrantsWhen we include negative values, the x and y axes divide the space up into 4 pieces:Quadrants I, II, III and IV...
