These headlines refer to the decision in which Supreme Court case?​

Dred Scott v. Sandford

Explanation:

In the Dred Scott v. Sandford case, the Supreme Court ruled that the Missouri Compromise was unconstitutional and that African Americans were not citizens under the US Constitution and therefore did not have the same rights and privileges that US citizens had. This allowed slavery to prevail and to have more power, which is where the "The Triumph of Slavery" headline comes from. This Supreme Court case overall was a massive gain to slavery, but a huge loss to actual slaves.

according to the quotation from booker t. washington's 1895 atlanta compromise speech.

in the great leap from slavery to freedom . . the masses of us are to live by the production of our hands . . we shall prosper . . as we learn to dignify and glorify common labor.

washington believed that  hard work had its own kind of dignity.
