數(shù)軸上的點(diǎn)與下列各數(shù)中的什么數(shù)一一對(duì)應(yīng)

A.整數(shù)

B.有理數(shù)

C.無(wú)理數(shù)

D.實(shí)數(shù)

試題答案

D

試題解析

根據(jù)實(shí)數(shù)與數(shù)軸的對(duì)應(yīng)關(guān)系解答.

解答:每一個(gè)數(shù)都可以用數(shù)軸上的點(diǎn)來(lái)表示;反過(guò)來(lái)數(shù)軸上的每一個(gè)點(diǎn)都表示一個(gè)實(shí)數(shù).即實(shí)數(shù)與數(shù)軸上的點(diǎn)是一一對(duì)應(yīng)的.

故選D.

點(diǎn)評(píng):本題考查了實(shí)數(shù)與數(shù)軸的對(duì)應(yīng)關(guān)系:實(shí)數(shù)與數(shù)軸上的點(diǎn)是一一對(duì)應(yīng)的.
