Question

The graph shows a journey in a car. Which of the statements most likely describes the start of the journey at the portion of the graph labeled I?
A. The car travels the same distance per unit of time because the portion shows a linear, increasing function.
B. The car travels different distances per unit of time because the portion shows a linear, increasing function.
C. The car travels the same distance per unit of time because the portion shows a nonlinear, increasing function.
D. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.

Answer 1

Answer:A

Step-by-step explanation:

Answer 2

Answer:

A. The car travels the same distance per unit of time because the portion shows a linear, increasing function.

Step-by-step explanation:

The portion of the graph labelled I is linear increasing function. So, the slope is constant. The slope is the the ratio of change in the quantity of y-axis to that of x-axis.

Here distance is plotted in the y-axis and time in the x-axis.

So, the slope here is Distance covered/ Time, which is nothing but the speed of the car.

Since the slope is constant, the car is travelling at a constant speed in the portion of the graph labelled I, which means, the car travels the same distance per unit of time in the portion I.
