Which equation is equivalent to y – 6 = –12(x + 4)?
(1 point)
Responses
y = –6x – 48
y = –6 x – 48
y = 6x – 48
y = 6 x – 48
y = –12x – 42
y = –12 x – 42
y = –12x – 54
y = –12 x – 54

Which equation represents the line that passes through the points (6, –3) and (–4, –9)?
(1 point)
Responses
y + 4 = (x + 9)
y + 4 = Image with alt text: three-fifths ( x + 9)
y + 4 = (x + 9)
y + 4 = Image with alt text: five-thirds ( x + 9)
y - 3 = (x + 6)
y - 3 = Image with alt text: three-fifths ( x + 6)
y + 3 = (x – 6)
y + 3 = Image with alt text: three-fifths ( x – 6)

The correct answer is:
y - 3 = (x + 6)
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?
(1 point)
Responses
p = 4x + 50
p = 4 x + 50
p – 450 = 4(x – 15)
p – 450 = 4( x – 15)
p – 15 = 4(x – 450)
p – 15 = 4( x – 450)
p = 4x + 15
p = 4 x + 15

The correct answer is:
p = 4x + 15
