Final answer:
Dr. King uses metaphors and imagery to express his feelings about equal civil rights for African-Americans.
Step-by-step explanation:
Dr. King uses figurative language to support his feelings about equal civil rights for African-Americans by employing various rhetorical devices, such as metaphors and imagery. For example, in his famous "I Have a Dream" speech, he states, "America has given the Negro people a bad check, a check which has come back marked 'insufficient funds.'" This metaphor of a bad check highlights the injustice and inequality faced by African-Americans in America. Additionally, Dr. King uses vivid imagery when he says, "I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character." This imagery emphasizes his vision of a future where racial equality exists. These figurative language techniques effectively support Dr. King's passion for equal civil rights for African-Americans.
