Answer 1

Answer:

linear equation
$x - y = 20$
Solution:

As pocket money of Aastha is x rupees

her expenses are y Rupees

Saving she want to be 20 rupees

So this can be expressed in linear equation as

$x - y = 20$
Now to plot graph of this equation.

put x=0

$0 - y = 20 \\ \\ y = - 20$
one point is (0,-20)

For second point put y=0

$x - 0 = 20 \\ \\ x = 20$
second point (20,0)

Mark these points on graph and join them

Aastha love her mother so much that's to show that love she wants to save money from the pocket money she got.
