Question

Interest on deposits for a year
Deposit (in Rs)1000 2000 3000 4000 5000.simple interest (in Rs)
80 160 240 320 400
1)Does the graph pass through the origin

Answer 1

The graph of amount of deposit (x) vs interest earned after one year (y) will be a straight line passing through origin (0,0).

Step-by-step explanation:

The deposits are given to be (in Rs.) 1000, 2000, 3000, 4000, 5000.

And the interest earned after one year on those deposits are (in Rs.) 80, 160, 240, 320, 400.

Therefore, the amount of interest is increasing uniformly with the amount of deposits.

So, the relation is linear between the deposit amount and the interest amount after one year.

Again, we know that if the deposit amount is zero then the interest earned from this will also be zero, whatever be the duration of the deposit.

Therefore, the graph of the amount of deposit (x) vs interest earned after one year (y) will be a straight line passing through the origin (0,0). (Answer)
