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

The statement best describes Cheryl's computer is option C. Cheryl accelerated to 65 mph, drove at a constant speed for 5.5 minutes, and then decelerated to 45 mph.
<h3>How to find the function which was used to make graph?</h3>
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
If we know that the function crosses the x-axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
Let's assume the graph of Cheryl's commute was like the one below.
We can see that she started at 0 mph.
One minute later, she was up to 65 mph, so she had accelerated (increased her speed).
At 6.5 min (5.5 min later) her speed was still 65 mph therefore, she was driving at a constant speed.
Over the next 2.5 min, her speed dropped to 45 mph, therefore she was decelerating.
