Sistema Cartesiano de Coordenadas

IFRN / CM - Matemática 1
Duas retas perpendiculares entre si (ângulo de 90° entre elas) e orientadas a partir do ponto de intersecção ( 0 , 0 ), também chamado de [b]origem[/b], formam um [b]Sistema Cartesiano de Coordenadas[/b]. [br][br]Estas retas concorrentes (que se encontram na origem), dividem o plano cartesiano em quatro regiões que são chamadas de [b]quadrantes[/b], e são enumerados de acordo com a figura

1) Movimente livremente o ponto P e analise os valores de suas coordenadas:
Questões para Reflexão:
a) Quando o ponto P está sobre o eixo horizontal (Eixo X), podemos afirmar que o valor da [b]segunda coordenada[/b] (y = ordenada) é sempre?
b) Quando o ponto P está sobre o eixo vertical (Eixo Y), podemos afirmar que o valor da[b] primeira coordenada[/b] (x = abscissa) é sempre?
c) Quando o ponto P está no [b]1º Quadrante[/b], podemos afirmar que:
d) Quando o ponto P está no [b]2º Quadrante[/b], podemos afirmar que:
e) Quando o ponto P está no [b]3º [/b]ou no[b] 4º Quadrante[/b], podemos afirmar sempre que:
