## ashleylynn Group Title 1. Which equation is equivalent to y – 6 = –12(x + 4)? a.y = –6x – 48 b.y = 6x – 48 c.y = –12x – 42 d.y = –12x – 54 2. Which point is located on the line represented by the equation y + 4 = –5(x – 3)? a.(–4, –5) b.(–5, –4) c.(3, –4) d.(–3, 4) 3. Which equation represents the line that passes through the points (6, –3) and (–4, –9)? a. y+4=3/4(x+9) b. y+4=5/3(x+9) c. y-3=3/5(x+6) d. y+3=3/5(x-6) 2 years ago 2 years ago

solve the equation .. can you do it?

2. ashleylynn Group Title

noo

3. sritama Group Title

|dw:1336107604262:dw|

4. ashleylynn Group Title

so the answer for that one is 4 =-12x-42

5. sritama Group Title

4 or y?

6. ashleylynn Group Title

sorryy i ment y

7. sritama Group Title

yes

8. ashleylynn Group Title

ohkay how do u do the second one?

9. sritama Group Title

for the 2nd one put the values of the points in the equation find which one is satisfying it

10. sritama Group Title

it is c

11. ashleylynn Group Title

(3,-4) ?

12. sritama Group Title

yes

13. sritama Group Title

when u have 2 points (a,b) and (m,n) the equation of the line passing through those is

14. sritama Group Title

|dw:1336108066496:dw|

15. ashleylynn Group Title

wait im sorryy i can't read that and i don't know where to plug in what numbers...

16. sritama Group Title

d

17. ashleylynn Group Title

ohkayy thank you !!!!!!!!!! i need help with one more. 4. The population of a city increases by 4,000 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 + 50 b.p – 450 = 4(x – 15) c.p – 15 = 4(x – 450) d.p = 4x + 15

18. sritama Group Title

wait a while, plz

19. ashleylynn Group Title

it's my last one and what do you mean?

20. sritama Group Title

i am requesting you to wait for sometime

21. ashleylynn Group Title

ohkayy

22. sritama Group Title

are you sure that the options are correct, i am getting p=390000+4000x

23. ashleylynn Group Title

yeah that's what i got no that's not in the options

24. sritama Group Title

oh, sorry i missed 'in thousand of people'... it is b

25. ashleylynn Group Title

Thank youuu!

26. sritama Group Title

welcome :)

27. ashleylynn Group Title

i have more but i doubt u wanna help me wth the steps

28. sritama Group Title

yes,post them
