Final answer:
The President's legislative powers include signing bills into law, vetoing bills, issuing signing statements, and requiring opinions of departmental secretaries. The President does not have the power of line-item veto.
Step-by-step explanation:
The President's legislative powers include the ability to sign a bill into law, veto a bill and return it to Congress, issue signing statements, and require opinions of departmental secretaries. However, the one legislative power that the President does not have is the line-item veto, which is the power to strike out specific portions of a bill while letting the rest pass into law.
