Q. How do I cite a PowerPoint presentation from my instructor in MLA format on my works cited page?

The MLA Handbook Plus gives guidance on citing slide material uploaded to a learning management system like Blackboard or D2L.   It shows this example for slides uploaded to a learning management system:

"Slides (Date)."  Name of class, taught by (teacher).  Name of Learning Management System, Name of School, Date Accessed, URL.

"Slides 040720."  Introduction to Digital Media Theory, taught by Kathleen Fitzpatrick. D2L, Michigan State U, 7 Apr. 2020, d2l.msu.edu/d2l/le/content/909183/viewContent/8746820/View.

Make sure you do appropriate hanging indent, font, etc.
