Question

A three-wheeler scooter charges Rs. 15 for first kilometer and Rs.8 each for every subsequent kilometer.
For a distance of 'X' kilometres, an amount of Rs. 'y' is paid.
Represent this situation algebraically as well as graphically.​​

Answer 1

Answer:8x+7

Step-by-step explanation:

The scooter charges Rs. 15  for first kilometer and Rs. 8 each for every subsequent kilometer.

Distance traveled =x km

So, Rs. 15 is paid for first kilometer.

And Rs. 8 each for every subsequent kilometer for the rest x−1 km

Total amount paid =15+8(x−1)

y=15+8x−8

y=8x+7

Answer 2

The 3 wheeler scooter charges Rs. $15$ for the first km and Rs. $8$ for each km after that.

Distance traveled = $x km$

So, Rs. $15$ is paid for the first kilometer.

And Rs. $8$ each for every subsequent kilometer for the rest x−1 km

The total amount paid $=15+8(x-1)$

$=>y=15+8x-8$

$=>y=8x+7$

Representation as graphically,

From the above expression,

The slope is $8$ and the y-intercept is $(0,7)$
