Jakita examines the ordered pairs ( 3/4, 2/3), (1/4, 2), (1, 1/2) and (1/2, 1), and determines the points form a direct variation with a k value of 1/2.

Which statements about Jakita's conclusion are true? Select two options.
A.) The points actually represent an inverse variation.
B.) The k value of the direct variation is actually 2.
C.) The ordered pairs can be represented by the function y = x/2
D.) The ordered pairs can be represented by the function y = 1/2x
E.) As one quantity increases, the other also increases.
