    Professora, uma dúvida:

    No exercício 3c, o x não seria negativo e o y positivo já que na bissetriz24 o quadrante II tem o x negativo e o y positivo? Se fosse bissetriz42 o x seria positivo e o y negativo? Não seria assim? Obrigado.

    Entendi a sua pergunta. Não importa onde você coloca o sinal negativo. O importante é colocar um contrário do outro. Assim, sabendo que em módulo, eles têm o mesmo valor, se vc obtiver resposta de x positiva, o y ficará negativo e se obtiver resposta de x negativo, o y ficará positivo. Quando começamos um exercício, não sabemos em que quadrante o número estará... Se for no segundo, x será negativo e y positivo, mas se estiver no quarto quadrante, o x será positivo e o y negativo. Certo?

    Professora, uma dúvida:

    o valor de Y vem primeiro e depois o X ? (y,x)

    ou o valor de X vem sempre primeiro? (x,y)
