  • Q5
    Rewrite in Standard Form: -6x - 9y = 10
    y = -3/2x - 10/9
    -6x - 9y = -10
    6x + 9y = -10
    3x + 2y = 10

  • Q6
    Rewrite in Standard Form: 1/2x - 5y = 4
    2x + 10y = 4
    x - 10y = 8
    x + 10y = 8
    x - 5y = 4

  • Q8
    Given (4 , -9) and a slope of 2, what is the equation for this line?
    y + 9 = 2(x - 4)
    y + 4 = 2(x - 9)
    y = 2x + 1
    y - 9 = 2(x + 4)

  • Q9
    An Uber costs $10 for pickup and $.15 for every mile traveled. Which equation below represents this situation?
    y = -.15x - 10
    y = x + 10
    y = .15x + 10
    y = 10x - .15

  • Q10
    You bought 4 bags of smarties and 2 bags of dumdums for $22.50. Which equation below represents this situation?
    4s - 2d = 22.5
    s = 2d + 22.5
    4s + 2d = 22.5
    d = 22.5s - 4
