填空题
若点P(3,x-1)到两坐标轴的距离相等,则点P的坐标为______.
答案
∵点P(3,x-1)到两坐标轴的距离相等.
①当3=x-1时,
解得x=4,
∴x-1=4-1=3,
点P的坐标为(3,3),
②当3=-(x-1),
解得x=-2,
∴x-1=-2,
∴点P的坐标为(3,-2),
综上所述,点P(3,3)或(3,-2).
故答案是:(3,3)或(3,-2).

∵点P(3,x-1)到两坐标轴的距离相等.
①当3=x-1时,
解得x=4,
∴x-1=4-1=3,
点P的坐标为(3,3),
②当3=-(x-1),
解得x=-2,
∴x-1=-2,
∴点P的坐标为(3,-2),
