    A.
    B.
    C.
    D.
    Hint

  2.   Simplify the equation.y = –2(x – 7) – (9 + 5x)
    A. y = –7x + 5 B. y = 3x – 16
    C. y = –16x + 3 D. y = 7x – 5
    Hint

  3.   Which equation is not the same as the other three?
    A. –5x = –y + 3 B. y + 5x = 3
    C. 5xy + 3 = 0 D. y – 3 = 5x
    Hint

  4.   Which equation is not the same as the other three?
    A. 6 + 2y = x B.
    C. D.
    Hint

  5.   Name a similarity and a difference among the three graphs below.
7x + y + 8 = 0
–7x + y + 8 = 0
–3xy – 8 = 0
    A. None of the graphs have the same slope nor the same y-intercept.
    B. The graphs have the same slope, but different y-intercepts.
    C. The graphs have the same y-intercept, but different slopes.
    D. The graphs have the same slope and y-intercept.
