## 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. 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 + 2 years ago 2 years ago

For problem 1, you want to first apply the distributive property to the right side, and then add 6 to both sides to isolate the y.

2. ashleylynn Group Title

ohkay then what?

3. ashleylynn Group Title

@nbouscal

4. nbouscal Group Title

If you've done that you should have the answer

5. ashleylynn Group Title

i got y-6=-12x+-48 @nbouscal

6. nbouscal Group Title

After the first step that's correct, then the second step is to add 6 to both sides to isolate the y.

7. ashleylynn Group Title

wait i don't get how to do that like so it would y=6x-48 ? @nbouscal

8. nbouscal Group Title

Nope. You have \(y-6=-12x-48\). So then you add 6 to both sides, which gives \(y-6+6=-12x-48+6\). Then you combine like terms to simplify it.

9. ashleylynn Group Title

y=-12x-42 @nbouscal

10. nbouscal Group Title

That's correct.

11. ashleylynn Group Title

ohkay next one

12. ashleylynn Group Title

@nasavivek

13. nasavivek Group Title

@ashleylynn ... for 1st one ans is y= -12x-42

14. ashleylynn Group Title

yeah i know i mean what do i dooo for the second problemmm @nbouscal

15. nasavivek Group Title

@ashleylynn ..for 2nd ans is (-5,-4)

16. ashleylynn Group Title

thanks and for the 4th ? @nbouscal
