Shown above is a typical E1 elimination reaction.
The Br- leaves in the first step to generate a secondary carbocation, which rearranges into a tertiary carbocation by shift of alkyl group(s) from adjacent carbon atom. Loss of a hydrogen in the final step gives the alkene products shown above.
A total of 8 products are drawn below.
