She was born in 1908, in Atlanta. In 1918, Slaton moved with her family to Detroit. In the same city, she would receive her first job in 1933, at the Detroit City Hall, working as a secretary. This position made her one of the first African-Americans in the government of Detroit to hold a white-collar job. She left the position at the onset of World War II, and promptly enrolled in Wayne State University. After graduation, she worked as a special education teacher in the Detroit Public Schools schools system. Slaton not only became heavily involved in helping black men and women, but, in 1942 over a dispute involving the Sojourner Truth Housing Project, she took up law. After nine years, she graduated at the University of Detroit Law School and worked for Detroit as a lawyer. In 1972 she was appointed the first woman to be a referee in the Recorder's Court Traffic and Ordinance Division. Six years later, she became a Common Pleas Judge in the City of Detroit, and eventually retired. After a short retirement, she chaired the State Crime Victims Compensation Board, and would work in similar capacities until her death in 1983.
