Polish has no separate words for a or the. Definiteness or indefiniteness comes from context and word endings. So Moja walizka jest ciężka simply means My suitcase is heavy without adding any article.

What is jest in this sentence?

Jest is the 3rd person singular present form of the verb być (to be). It corresponds to is in English and links the subject (Moja walizka) with the description (ciężka).

How do I know to use moja instead of mój or moje?

The possessive pronoun mój changes form to agree with the gender and number of the noun in the nominative case: masculine is mój, feminine is moja, and neuter or plural is moje. Since walizka is feminine singular, you use moja.

What case is walizka, and why?

Walizka is in the nominative case because it's the subject of the sentence (the thing that's heavy). In Polish, subjects are marked by the nominative case.
