Only a transitive verb (a verb with a direct object) can be in the passive voice.

To change a sentence from active to passive voice:

1) Move the direct object to the subject position.

2) But verb “to be” in the same verb tense as the original active voice sentence.

3) Add the past participle of the verb from the original active voice sentence.
