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 +

    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.

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

    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.
