A line parallel to the given one will have the same slope, 0.5. For the purpose here, it is convenient to start with a point-slope form of the equation, then simplify. For slope m and point (h, k), the equation of the line can be written as
... y = m(x -h) +k
We have m=0.5, (h, k) = (-9, 12), so the equation is ...
... y = 0.5(x +9) +12
... y = 0.5x +16.5
Answer:
C) 6
Step-by-step explanation:
From the given data we can find the constant of proportionality by dividing The number of people by number of cars.
Constant of proportionality =
Taking any point from the table will give the same constant of proportionality as they are proportional quantities.
Constant of proportionality =
This can be written as 6 people per car.
For 10 cars, number of people will be ==60 people.
