1. The population of a city increases by 4000 people each year. In 2025, the population is projected to be 450,000 people. What is an equation that gives the city's population p (in thousands of people) x years after 2010?

A) p=4x+450

B)p-450=4(x-5)

C)p-15=4(x-450)

D) p=4x+15

i keep getting a different answer. somebody pls help me!?? thanks

  1. You have a point (15,450) and a slope (4), so the line should be

    p-450 = 4(x-15)

    I'd say (B) with a typo

  4. 1. y-6 = -12(x + 4)
    C. y = -12x - 42

    2. y + 4 = -5(x - 3)
    C. (3, -4)

    3. (6, -3) and (-4, -9)
    D. y + 3 = 3/5(x - 6)

    4. The population of a city increases by 4,000...
    B. p - 450 = 4(x - 15)

    5. y - 3 = -3/2(x + 4)
    B. The graph in which the line passes through points: (2, -6) (-6, 6)

    I put C instead of B for 5 as everyone said, and it was wrong. You don't have to believe me, but you'll see for yourself.

  16. 5. y - 3 = -3/2(x + 4)
    B. The graph in which the line passes through points: (2, -6) (-6, 6)

    If you have a chart ( (-2, 0), (-1, -2), (0, -4), (6, -16) ) for number 5, here is your answer:
    C. y+2=-2(x-1)

    Everything else was the same with it being 1. C, 2. C, 3. D, 4. B.
