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)

    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
