Question

plot the following points in a graph sheet and join them by using straight lines . What can u say abt the line formed?
(1,-2) (3,-1) (5,0)​

Answer 1

Answer:

Answer:

Step-by-step explanation:

Let us think of a number say 3.

On doubling 3 we get 6.

Adding 9 with the result we get 15.

On subtracting 3 we get 15-3 = 12

Dividing 12, we get 6.

Subtracting 3 from 6 we get 3.

Why do we get the same number?

This is a part of mathematical modelling. The way we frame a question, in some tricks, we just formulate the same, to get the reverse number back. This can be done by subtraction, addition or any arithmetic operation, by doubling, tripling etc ..

We can relate it to a tree formed in XML as well, that's mathematical modelling.

It will form a straight line.
