C.) Coordinate of x is (10, 8)
In short, Your Answer would be: Option C
Hope this helps!
Answer: 
Step-by-step explanation:
This car follows a line, hence its motion can be modeled by the Line equation.
In fact, we already have two points of the line, if we call
the time in hours and
the traveled distance in miles:
Point 1:
Since we are told the car's initial position is 300 miles in the time 0 h
Point 2:
Since we are told the car's final position is 180 miles after 3h

<u>Let's find the Slope
:
</u>
This is the slope of the line
Now, the equation of the line is:
We already know the slope, now we have to find the intersection point with the y-axis (
) with any of the given points. Let's choose Point 1:
Isolating
:
Then, the equation of the line is:
This is the derivitive of x
critical points are where the first derivitive is equal to 0 or where the derivitive doesn't exist
ok, it is 0 at x=0 and 2
so I is true but not II
the point of inflection is where the slope of the 1st derivitive=0
that is at x=1
so III is true
I and III
4th option
The answer is ZBM.
Have a lovely day!
