SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.

Show that the two ordered pairs are solutions to the given equation. Then use the graph of the two points to determine another solution. Answers may vary.

31) y = x - 1; (5, 4), (3, 2)

32) y = x + 2; (0, 2), (-2, 0)

33) y = (1/2)x + 3; (0, 3), (-6, 0)

34) y = (1/2)x - 4; (4, -2), (0, -4)

35) 2x + y = 6; (1, 4), (4, -2)

36) x + 2y = 8; (2, 3), (-4, 6)

37) 6x - 2y = 10; (0, -5), (2, 1)

38) 3x - 3y = 6; (-3, -5), (3, 1)

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.
