The changing speed of a car is modeled by the function S(t) = −35t + 30, where t is time in seconds. Interpret the model
Flauer [41]

The car has an initial speed of 30 units and is slowing down by 35 units per second ⇒ answer C

Step-by-step explanation:

The form of the linear function is f(x) = m x + b, where

  • m is the rat of change
  • b is the initial value

The changing speed of a car is modeled by the function s(t) = -35t + 30, where t is time in seconds.

We need to interpret the model

∵ The changing speed of a car is modeled by s(t) = -35t + 30

- Compare between the model and the form of the linear function

∴ m = -35 and b = 30

∴ The initial speed is 30 units

∴ The speed is changing by -35 units per second

- If the value of change of the speed is negative, means the

  car is slowing down by this rate

∴ The car is slowing down by 35 units per second

The car has an initial speed of 30 units and is slowing down by 35 units per second

Since the graph is a straight line, its equation is of the form;

y = mx + c
Where m is the slope and c is the y intercept

We can use any two points on the straight line to find the value of m and c.

Let us use (0,30) and (4,150)

m =  \frac{150 - 30}{4 - 0}
This simplifies to,

m =  \frac{120}{4}  = 30
Let us substitute the value of m to obtain,

y = 30x + c
Substitute any of the points to find c. It is easier to use (0,30).

30 = 30(0) + c
c = 30
The equation of the graph now becomes,

y = 30x + 30
So in 10 weeks Ben will collect,

y = 30(10) + 30
y = 300 + 30
y = 330
Ben will collect 330 papers.


You can also use any two points to find the equation of this line.
