O que \303\251 um quadrante?Podemos atribuir coordenadas a qualquer ponto em um plano usando duas retas numeradas que se interseptam em \303\242ngulos retos. Essas duas retas num\303\251ricas, cada qual chamada eixo (no plural eixos), dividem o plano em quatro se\303\247\303\265es, chamados quadrantes. Comumente, o eixo x \303\251 a reta horizontal e o eixo y a reta vertical.O ponto onde os eixos x e y se interseptam \303\251 a origem, com coordenadas LUklbXJvd0c2Iy9JK21vZHVsZW5hbWVHNiJJLFR5cGVzZXR0aW5nR0koX3N5c2xpYkdGJzYlLUkobWZlbmNlZEdGJDYlLUYjNictSSNtbkdGJDYlUSIwRicvJStleGVjdXRhYmxlR1EmZmFsc2VGJy8lLG1hdGh2YXJpYW50R1Enbm9ybWFsRictSSNtb0dGJDYuUSIsRidGNEY3LyUmZmVuY2VHRjYvJSpzZXBhcmF0b3JHUSV0cnVlRicvJSlzdHJldGNoeUdGNi8lKnN5bW1ldHJpY0dGNi8lKGxhcmdlb3BHRjYvJS5tb3ZhYmxlbGltaXRzR0Y2LyUnYWNjZW50R0Y2LyUnbHNwYWNlR1EmMC4wZW1GJy8lJ3JzcGFjZUdRLDAuMzMzMzMzM2VtRidGMEY0RjdGNEY3RjRGNw==.
