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

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

2. bobby

you sure

3. hi

Steve, there was a typo. :)

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)
